I am trying to simulate a plane wave with either S or P polarisation incident upon a nanoparticle on a substrate at various angle of incidence (phi and theta). Following the Scatterer on a Substrate model I have managed to do this for a S polarised plane wave using the follwing port conditions:
INCIDENT
x| -sin(phi)*exp(-i*(kbx*x+kby*y))
y| cos(phi)*exp(-i*(kax*x+kay*y))
z| 0
Propogation| abs (kaz)
TRANSMITTED (Through Substrate)
x| -sin(phi)*exp(-i*(kbx*x+kby*y))
y| cos(phi)*exp(-i*(kbx*x+kby*y))
z| 0
Could somebody please explain how this is derived for the model as the pdf doesnt really explain this. Also how would i modify this to have P polarisation incident?
Many Thanks Josh

I think I may have found the solution to this after reading the Fresnel Equation Model. In there they simply switch between TE and TM polarisation by changing the port input quantity from electric field to magnetic field. Thanks anyway
