Finite-Difference Time-Domain simulation of EM waves — click to place source
FDTD (Yee 1966): staggered E and H fields updated alternately in time.
∂Ez/∂t = (1/ε)(∂Hy/∂x − ∂Hx/∂y)∂H/∂t = −(1/μ)∇×E.
Courant condition: c·Δt/Δx ≤ 1/√2 for stability. Click to add point source; Add Wall draws reflectors.
