README.md

Meep is a free and open-source software package for electromagnetics simulation via the finite-difference time-domain (FDTD) method spanning a broad range of applications.

Key Features

Free and open-source software under the GNU GPL.
Complete scriptability via Python, Scheme, or C++ APIs.
Simulation in 1d, 2d, 3d, and cylindrical coordinates.
Distributed memory parallelism on any system supporting MPI.
Portable to any Unix-like operating system such as Linux, macOS, and FreeBSD.
Precompiled binary packages of official releases via Conda.
Variety of arbitrary material types: anisotropic electric permittivity ε and magnetic permeability μ, along with dispersive ε(ω) and μ(ω) including loss/gain, nonlinear (Kerr & Pockels) dielectric and magnetic materials, electric/magnetic conductivities σ, saturable gain/absorption, and gyrotropic media (magneto-optical effects).
Materials library containing predefined broadband, complex refractive indices.
Perfectly matched layer (PML) absorbing boundaries as well as Bloch-periodic and perfect-conductor boundary conditions.
Exploitation of symmetries to reduce the computation size, including even/odd mirror planes and 90°/180° rotations.
Subpixel smoothing for improving accuracy and shape optimization.
Custom current sources with arbitrary time and spatial profile as well as a mode launcher for waveguides and planewaves, and Gaussian beams.
Frequency-domain solver for finding the response to a continuous-wave (CW) source as well as a frequency-domain eigensolver for finding resonant modes.
ε/μ and field import/export in the HDF5 data format.
GDSII file import for planar geometries.
Field analyses including discrete-time Fourier transform (DTFT), Poynting flux, mode decomposition (for S-parameters), energy density, near to far transformation, frequency extraction, local density of states (LDOS), modal volume, scattering cross section, Maxwell stress tensor, absorbed power density, arbitrary functions; completely programmable.
Adjoint solver for inverse design and topology optimization.
Visualization routines for the simulation domain involving geometries, fields, boundary layers, sources, and monitors.
