Electrodynamics#
Finite-difference time-domain (FDTD) solutions of Maxwell’s equations on a Yee grid, in 1D and 2D, plus a graded-conductivity absorbing boundary in the spirit of Berenger’s Perfectly Matched Layer. Also includes animated demos of a Hertzian oscillating dipole antenna, a wave crossing a dielectric slab, and a standing TM cavity mode.
