How to Create a Linearly Polarized Electromagnetic Wave (Light) Source.

Greetings,

I am a newcomer to COMSOL and I am seeking assistance in setting up a linearly polarized electromagnetic wave light source. To provide some context, my project involves developing a basic model with the objective of studying the reflectance and transmittance characteristics of different materials exhibiting distinct refractive indices. I intend to approach this investigation through the application of the Fresnel Equations. Currently, I have progressed to the stage of creating a cylindrical geometry representing a layer composed of Silica glass. However, I am encountering challenges in establishing the light source.

Any guidance or support would be greatly valued.

Use the scattered field formulation and set the background field to Linearly Polarized Plane Wave. See attached screen shot.

Thank you! It works. If it's no bother, can you also consult on my other recent problem on meshing. The discussion post is titled, "Meshing Error" and you can probably find it by searching the title or my name (Collins Kariuki).
