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.

Dear Edgar J. Kaiser,

Thank you for the reply and suggestion. I am using the following components of input Electric field for P-wave E(cos (incident angle), 0, sin(incident angle)) in COMSOL 6.1 but results are with very high intensity but this is not the case in experiment. I have also tried with E(1,0,1) for P-wave reflection, result is again the same. While for same model with Electric Field components for S-Wave E(0,1,0) works well. Please suggest any solution for P-waves Reflection. Thanks in anticipation.
