I would like to compute the scattered wave off a PEC obstacle (such as a polyhedron or ellipsoid) by an incoming time harmonic plane EM wave. The wavelength is much smaller than the scale of the obstacle (such as 1/100). If I choose the wave optics module -> em wave -> frequency domain then the mesh must be very fine and the computation can't be done in a PC. The wave optics module -> em wave -> beam envelopes model is also not suited since the tip says

The physics interface can be used efficiently for unidirectional and bidirectional propagation of electromagnetic beams. However, for optical scattering phenomena, where the field is scattered into many different directions, the Electromagnetic Waves, Frequency Domain interface is better suited.

In my problem the beams are split in more than two directions.

Are there any other better methods for this problem?
