I was trying to simulate particle sorting of gold immersed in water medium with a glass substrate. Here, I want to apply two plane wave source incident on the glass substrate together. The two light sources are of different wavelenth and the parametric sweep would be used to vary radius of the gold particle. So far, while working with single plane wave source, I enter the wavelength in the frequency part ie (speed of light/wavelength). However, now, as there are two sources of two different wavelength, I am facing problem. Some guideline regarding this will be highly appreciated.
Thanks
