** Previous:** 6.2.2 Second Maxwell Equation

Both vertical field components
*E*_{z, nm}(*z*) and
*H*_{z, nm}(*z*) are analytically
related to the lateral ones. Hence they can be eliminated
in (6.15) and (6.18) and we end up at an
ODE system comprising only the Fourier coefficients
of the lateral field components:
