I'm doing PML simulation, and while I was looking for correct geometry for my layers of propagation, I got question.My device, has two vibration sources, and this vibration will propagate through the medium and diminish.I am trying to draw my medium as a cylinder or hemisphere, but since there are two vibration sources, center of cylinder/hemisphere is in equal distance between two vibrating sources.here is the picture of how it looks like.This is 2D version, but I am simulating this device in 3D version.The vibration source has out of plane waveform.Is it okay to simulate like this? I'm afraid this will give incorrect result since vibration sources are not at the center of cylinder/hemisphere.Or, do I have to cut my device in half and put only one vibrating source on the propagating medium? (symmetric condition should be imposed on the half of resonator device)This second method, I think it seems unrealistic, because it excludes the presence of other vibrating source which will cause interference, however, I saw number of papers simulate their device with two vibrating sources such way.
