scikit-rf - v1.0.0

The major release 1.0.0 of scikit-rf is the result of 14 years of developement by around 80 contributors. In the recent months, the codebase and its API has been reorganized, cleaned and optimized, to provide a robust and well-tested RF/Microwave engineering package.

The version 1.0.0 does not include major changes with respect to the previous versions. This number 1.0.0 just aims to show for current and future users, that the scikit-rf package has now reached a significant level of maturity, a sufficient stable and performant state, ready for production use. It means that the developers consider scikit-rf to be ready for a widespread adoption.

Of course, scikit-rf development will continue, with new features, bug fixes, improved performances, in its subsequent versions.

Looking ahead to future release, we have releases a survey is intended for all the users of scikit-rf, in order for the developers to get some feedback, to determine what are the functionalities used the most and the less, the ones which could be improved, and to determine the directions for the future of the package. Thank you for your time in answering this survey. This should take 5 minutes and your feedback will be very useful.

What's Changed

Important Changes in `Media`

Refactor media to simplify line creation by @mhuser in https://github.com/scikit-rf/scikit-rf/pull/727

The Media class has been refactored to simplify the API and avoid confusions related to the impedances. The z0 property now returns by default the Characteristic Impedance of the media (also available from z0_characteristic) if the property z0_override is defined, z0 returns z0_override instead of the Characteristic Impedance.

The embed argument and the parameters Z0 (capital) have been deprecated. If the property z0_port is defined, all lines will be renormalized from z0 to z0_port, like in a measurement with z0_port. Please refer to the Media tutorial more additional information and a clear explanation of the different between port and characteristic impedances.

New Features

Add gain properties by @keikawa in https://github.com/scikit-rf/scikit-rf/pull/908

New properties have been added to a Network: maximum stable gain (max_stable_gain), Maximum available power gain (max_gain) and Mason's unilateral gain (unilateral_gain)

scikit-rf - v0.24.1

This release contains new features for time gating, make qtapps runable again and fixes related to matplotlib dependency.

Note that new warnings related to the default frequency and time unit are now generated if the frequency or time units are not explicitly passed. Indeed, SI units will used by default for frequency (Hz) and time (s) in future versions of scikit-rf, instead of GHz and ns as presently. It is thus recommended to pass explicitly the units in order to avoid surprises in future versions...

New Features

time.time_gate() has a new parameter method added, to choose how to perform gating either by convolution, by FFT (band-pass mode), or by RFFT (low-pass mode). Defaults is FFT. Also, another parameter fft_window is added, which enables frequency-domain windowing in case of FFT and RFFT mode. The default is a Hann window, but windowing can be disabled by setting fft_window=None. by @Vinc0110 in https://github.com/scikit-rf/scikit-rf/pull/770
qtapps are now runable again by @FranzForstmayr in https://github.com/scikit-rf/scikit-rf/pull/790

scikit-rf - Changes in Connect, Vector Fitting, Type hints and many more

This new version of scikit-rf includes multiple bug fix and changes under-the-hood, that should not affect users except for users of the connect() method with N-port Network.

`Connect`

The automated port renumbering in connect() was quite unintuitive since 2020 and has been corrected in #448 by @hohe. To make things as clear as possible, special tutorial dedicated to Network connections has been added to the documentation (@jhillairet).

Vector Fitting

#469 & #473 @Vinc0110 fixes two bugs in the vector fitting algorithm and adds some documentation and tests.
@FranzForstmayr removed the mandatory matplotlib dependency in Vector Fitting in #444
following a suggestion in the mailing-list @Vinc0110, added optional Axes parameters to the plotting functions in vectorFitting.py to control the output with matplotlib in #450.

Type Hints

@FranzForstmayr in #451 updated a lot of the function & method definitions to add type hints to improve the quality of the autosuggestions in IDEs.

Documentation

@NikoDaGreat Fixed math typesetting in network.chopinhalf in #465
@jhillairet refreshed the main Github welcome page in #445. In addition, please note that a suggestion box has been added: please send us your suggestions/wishes/comments!
@NikoDaGreat fixed some typos in #446
@jhillairet correct documentation figures in #452 and #453

Improvements and bug fix

#445 @FranzForstmayr improved the Z0 setter/getter and also add new tests detailed the various cases
#457 @FranzForstmayr (contributor of the month!) fixed reading HFSS files from StringIO.
#458 + #459 @jhillairet fix NetworkSet zip file reading bug introduced by StringIO compatibility + add NetworkSet tests and fix continuous integration of the notebooks
#460 @Vinc0110 fixes the generated API docs of the VectorFitting class, which were missing the plotting functions.
#461 @FranzForstmayr update and tests to mathFunctions.py
#472 @luar123 fixes a bug in write_touchstone when the port names are written: The first port should be Port[1] instead of Port[0].

scikit-rf - End of Python 2 support, subnetwork and circular waveguide media

The support of Python 2.7 has been dropped with this version (PR#436 from @JAnderson419). For the moment, only the Travis and GitHub Actions testing have been dropped, the Python2 parts of code still exist and remain to be cleaned one day.

New Features

subnetwork

Creating the rf.subnetwork() function and Network.subnetwork() method for creating sub-Network for a given list of port indices. (PR #423 from @jhillairet)

As an illustration, below three 2ports subnetwork are extracted from a reference 3ports Network. These 3 subnetworks are after recombined into a 3ports Network.

```python import skrf as rf

3 port Network

tee = rf.data.tee

2 port Networks as if one measures the tee with a 2 ports VNA

tee12 = rf.subnetwork(tee, [0, 1]) # 2 port Network from ports 1 & 2, port 3 matched tee23 = rf.subnetwork(tee, [1, 2]) # 2 port Network from ports 2 & 3, port 1 matched tee13 = rf.subnetwork(tee, [0, 2]) # 2 port Network from ports 1 & 3, port 2 matched

recreate the original 3 ports Network from the thee 2-port sub-Networks

ntwlist = [tee12, tee23, tee13] tee2 = rf.ntwoports2nport(ntw_list, nports=3) print(tee2 == tee) # --> True ```

Circular waveguide media (`media.CircularWaveguide`)

Added circular waveguide (single mode homogeneous filled) Media from @scimax (PR #376). Also made some corrections to some rectangular waveguide formuale (cutoff) python # In the following example an ideal waveguide of 2.39 mm diameter is # constructed for the high W band, operated in the fundamental TE11 mode. # If no conductivity is provided the walls are treated as perfect # electric conductors. freq = rf.Frequency(88,110,101,'ghz') rf.CircularWaveguide(freq, r=0.5 * 2.39e-3)

Improvements of existing features

Network() can now supports StringIO for filename from @arsenovic (PR #433)
write port names to Touchstone files (as comment) from @luar123 (PR #428
Improve Error handling for step/impulse responses from @FranzForstmayr (PR #435, fixes #434). Now throws a:
- ValueError if one wants to calculate step or impulse response with an Network with more than one port
- NotImplementedError if one wants to calculate step or impulse response If used with non equidistant sampled frequency vector

Documentation

Fixing documentation notebooks from @jhillairet (PR #425)
Notebook tests are included using nbsmoke (but do not count for coverage) from @ema00 (PR#424, fixes partly #114)
Documentation improvements from @arsenovic (PR #433)

Fixed Bug

Use relative paths for import from @luar123 (PR #438)
Fix rf.io.Touchstone.get_comment_variables() which was cropping decimals from @JAnderson419 (PR #427, fixes #426 )
Matplotlib backend reconfiguration from @Vinc0110 (PR #420, fixes #419):
- Disabling the matplotlib backend reconfiguration in plotting.py (Edit: keeping it for Python2)
- Disabling invalid parameter interactive from matplotlib stylesheets, which were causing warnings in skrf.stylely()

scikit-rf - Vector Fitting algorithm Addition and Other Improvements

New Feature : Vector Fitting

This version 0.16.0 integrates a new feature from @Vinc0110 (PR #416). It adds the class VectorFitting, which provides a Python implementation of the Vector Fitting algorithm and various functions for the fit analysis and export of SPICE equivalent circuits. Avector fitting algorithm fits the frequency responses (S-matrix) in a Network to a sum of rational basis functions. Those rational basis functions can then be translated into equivalent passive or active impedances or admittances, enabling the modelling of the original frequency response in any kind of circuit simulator, e.g. SPICE simulations.

Documentation

PR #416 from @Vinc0110 also documents extensively the Vector Fitting features: - Vector Fitting Tutorials https://scikit-rf.readthedocs.io/en/latest/tutorials/VectorFitting.html - Mathematical Description - Equivalent Electrical Circuits - Equivalent Circuit of a Vector Fitted N-Port - References - 2 examples: - Measured 190 GHz Active 2-Port https://scikit-rf.readthedocs.io/en/latest/examples/vectorfitting/vectorfitting190ghzactive.html - Ring Slot https://scikit-rf.readthedocs.io/en/latest/examples/vectorfitting/vectorfitting_ringslot.html

Other Improvements

PR #415 from @JAnderson419 adds the pathlib.Path support to Network.
PR #412 from @wbarnha adds group delay feature to qt widget in networkPlotWidget
PR #410 and #417 from @jhillairet setups GitHub Actions for Continuous Integration (linting and tests), in addition of Travis.
PR #408 from @jhillairet allows users to define Frequency with a scalar value (ie. a unique frequency point)
