I am new to Comsol, so unfortunately I have little experience. I am trying to set up a very simple model in which I have a propagating plane wave in air, normally incident upon different materials with different geometries. It is to be a 2D model. Simply put: air medium, material (different types of plastic) with different geometries, then air. I am currently doing modeling in a ray tracing solver, but I wanted to compare the results with FDTD (patterned geometries are 2mm in size, corner cube reflectors). I want to know the reflectance / transmission of this plane wave as it interacts with these media. Plus I wanted the nice visualization of the plane wave reflecting for a presentation.
Here is a video (clip on the left), that I am trying to simulate. The plane wave can be a pulse, rather than continuous if that's easier to model.

Any advice as far as the type of solver, setup, variables, etc. would be great. I feel like I should be able to do this! As it doesn't appear to be anything to complex other than a plane wave incident upon a surface!
Thanks,
Dan
