Module fdtd 

Maxwell’s equations FDTD (Finite-Difference Time-Domain) solver.

Implements the Yee cell algorithm with leapfrog time-stepping for both 2D TM mode and full 3D electromagnetic field simulation.

Structs

FdtdGrid

Full 3D FDTD grid using the Yee staggered-grid scheme.

FdtdGrid2D

2D FDTD grid for TM (Transverse Magnetic) mode: Ez, Hx, Hy.

FdtdRenderer

Renders FDTD field data as colored glyphs. Blue = negative, Red = positive, brightness = magnitude.

MaterialGrid

Heterogeneous material specification for FDTD grids.
