Reply To: RCWA Phase extraction Problems

Hi Luca,
Somehow my previous reply was not successfully shown. Here again is my reply:
RCWA is a semi-analytical method with Fourier plane waves to decompose the physical fields in the device. Thus the phase reference of the amplitude coefficients is at the last/last material interface. The rest, eg the substrate and the superstrate will be considered as uniform, semi-infinite space.
