Microwave Filters

Hi all,

Can anyone tell me how to find out the power handling capability of Microwave Filters like interdigital bandpass filters?

Thanking you in advance.

Is there any IEEE paper or any journal on Microwave where power handling calculation is given for interdigital bandpass filters?

Is there any way to figure out the maximum power handling for interdigital bandpass filter through EM simulation or mathematical calculations using coupling coefficients?
