I am trying to simulate a simple structure to see the transmission of it. currently I have a plane source within a material of 1.5 refractive index. The source has a wavelength of 0.65um. When I do not have any material present, increasing the mesh accuracy gives me transmission near 1. When I include my material, it shoots over 1! I have been playing with mesh size, auto shut off time, boundary conditions etc. but yet to find any solution. Currently my source angle theta is zero.
Eventually I will be studying the effect of source angle, so have been using bloch BCs but as I do not have a broadband range opted not to use BFAST for my simulation.
I have tried to give an overview of what I am trying to achieve here and also attached my simulation file herewith. Kindly have a look and let me know what’s wrong in my simulation.
