Basic equations in some matter are written by ƏB rot E(x, t) + Ət div B(x, t) = 0, dweiwt 1 L μ(w) -8 where ·(x, t) = 0, rot B(x, w) f dwewte(w)div E(x, w) = 0, ·∞ ∞0 iw v² (w) -E(x, w) D(x, t) = Ď(x, w)e²wtdw, E(x,t) = (x, w) etwt dw, 00 Ď(x, w) = c(w)Ẽ(x, w). (B(x,w) = µ(w)Ĥ(x,w) as well (1) = (1) (2) 0, (3) (4) (5)
Using the potentials and the Lorenz gauge condition, E(x, t) = JA' Ət -(x, t) – grad o'(x, t), B(x, t) = rot A'(x, t), iw 1² (6) 0² (x, w) = 0₁ derive the wave equations for Ã'(x, w) and $'(x, w). div Ã'(x, w) + (6) (7) (8)
