E1 = E0exp(I(Wtk2x))E2 = E0

Question

E1 = E0exp(i(wt-k2x))

E2 = E0

exp(i(wt-k3x))

k2 = (w x n2)/c

k3 = (w x n3)/c

E1 and E2 are not orthogonal , however being two different eigenvectors of a symmetric matrix D1 and D2 are orthogonal . Prove this.

D is the electric displacement and E is the electric field.
