py-maxwell-fdfd

Solving Maxwell's equations via A python implementation of the 3D curl-curl E-field equations. This code contains additional work to engineer the eignspectrum for better convergence with iterative solvers (using the Beltrami-Laplace operator). You can control this in the main function through the input parameter $s = {0,-1,1}$

There is also a preconditioners to render the system matrix symmetric.

important notes about implementation

1. Note that arrays are ordered using column-major (or Fortan) ordering whereas numpy is natively row-major or C ordering. You will see this in operations like reshape where I specify ordering.

Examples

1. Plane Wave

2. Dipole in Vacuum

Future

Expect integration of this with ceviche for autograd
