Wave optics: Interference between two waves at different wavelength

Hello, I am trying (if possible) to simulate the interference pattern between two waves at different wavelengths. I am using the Wave optics module. As sources for my waves, I am using the Port boundary condition. I am using periodic ports and I am easily able to create the interference patterns I want keeping the two exciting waves at the same wavelength. Is there a way to do the same, but with two different wavelengths? Thank you in advance, Giulia di Fazio

Hi Giulia,
two options come to my mind:
Do it in time domain. However, I don't have wave optics and I am not sure if time domain is available in the module. It would be possible in RF.
Run two frequency domain studies at both wavelengths and add the solutions. You will need to decide at what phases you add the solutions.
In either case you won't get a static interference pattern as you do with one frequency. The pattern will be time or phase dependent.
