Conical mounting polarization implementation

[amsc1985]

Hi, Assume 1D grating, infinitely long grating along y axis and propagation in z. p polarized Electric field --> E is along the grating periodicity along x s polarized Electric field --> E is parallel to grating orientated along y

How should I define the E field to simulate a case where E is along grating periodicity (x direction), however, i want to vary angle of incidence along the grating?

Is the below correct implementation? S:SetExcitationPlanewave( {angle,90}, -- incidence angles (spherical coordinates: phi in [0,180], theta in [0,360]) {0,0}, -- s-polarization amplitude and phase (in degrees) {1,0}) -- p-polarization amplitude and phase

thanks, A

Hi,

Why did you you out 90 degrees for theta? When in tutorial for S4 it is written, when angles are 0, 0 the electric field is polarized along the x-axis for the p-polarization.
