Help, in comsol how to set a perfect plane wave (3D)?

  1. Jul 22, 2009 #1
    Hello everyone,

    I am recently doing some 3D scattering simulation. I use a plane wave as the illumination field,specifically i set a cubic configuration surrounded by PML. I chose one interior boundary and set it as Transition Boundary Condition and set the Ex=1 (x-polarized plane wave propagating along z direction). I also set the outmost boundary as PEC (perpendicular to Ex) and PMC (perpendicular to Hy). I have two questions in fact:

    (1) what boundary condition should i set in the Z direction (along the incident beam),PMC?PEC? or others ?

    (2) whether i am right to set the incident plane wave in such a way ?

    Thanks a lot !:rofl:
