meep

software package for FDTD simulation

Description

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

Its features include:

* 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.

* Arbitrary 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, and saturable gain/absorption.

* 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.

* Arbitrary current sources including a guided-mode launcher.

* Frequency-domain solver for finding the response to a

continuous-wave (CW) source.

* ε/μ and field import/export in the HDF5 data format.

* GDSII file import for planar geometries.

* Materials library containing predefined broadband, complex

refractive indices.

* Field analyses including Poynting flux, mode decomposition, near to far

transformations, frequency extraction, local density of states (LDOS),

modal volume, Maxwell stress tensor, arbitrary functions; completely

programmable.
