Dear fellows, I hope you are doing well.

Could you please guide how to define components for S-Wave and P-wave of Electric field incident at specific incident angle on 3D geometry in COMSOL 6.1.
It would be appreciated if some tutorial or example can be provided.

Thanks in anticipation.

S-and p-waves are a concept of seismic waves. They do not exist in electromagnetic waves.

Edit: Just saw, that the concept is used for light reflection and transmission on a surface. That is basic geometry. The s-component is parallel to the reflector surface and perpendicular to the propagation direction. The p-component is perpendicular to propagation direction and s-component. You can define a respective coordinate system in COMSOL.
