I have to find the transmission spectra(transmission vs wavelength) of a fabry perot cavity.I am new to comsol and I went through most of the models given in the documentation. I could not find an example where a transmission(or reflection) vs wavelength(or frequency) was calculated. From what I read, I came to know that the port boundary conditions are to be used. But I couldnt find any material that gave me more info about . if anybody can, please tell me how to do it, or any link to some reference material. Thank you
