Radiation resistance of a plate interacting with air

Hello everyone! I would simulate in Comsol the interaction between a vibrating plate sourrounded by the air in the near field of an anechoic chamber (to simulate the anechoic chamber I have set the acoustic boundary conditions as hard wall boundary conditions). The purpose is to detect the Radiation Resistance Matrix RRM defined as RRM=Re{p/u_Z} in a very large frequency range. Has anyone dealt with a similar problem?

You can set up an average operator on the plate surface and find the two variables to divide from there.
