**fdfd_tools** is a python package containing utilities for
|
|
|
|
|
creating and analyzing 2D and 3D finite-difference frequency-domain (FDFD)
|
|
|
|
|
electromagnetic simulations.

**Contents**
|
|
|
|
|
* Library of sparse matrices for representing the electromagnetic wave
|
|
|
|
|
equation in 3D, as well as auxiliary matrices for conversion between fields
|
|
|
|
|
* Waveguide mode solver and waveguide mode operators
|
|
|
|
|
* Stretched-coordinate PML boundaries (SCPML)
|
|
|
|
|
* Functional versions of most operators
|
|
|
|
|
* Anisotropic media (eps_xx, eps_yy, eps_zz, mu_xx, ...)
|

|
This package does *not* provide a matrix solver. The waveguide mode solver
|
|
|
|
|
uses scipy's eigenvalue solver; I recommend a GPU-based iterative solver (eg.
|
|
|
|
|
those included in [MAGMA](http://icl.cs.utk.edu/magma/index.html)). You will
|
|
|
|
|
need the ability to solve complex symmetric (non-Hermitian) linear systems,
|
|
|
|
|
ideally with double precision.
