Hi, I am quite new to comsol. My problem is fairly simple. I want to simulate an incident plane wave in 2D using RF module and calculate Fresnel Reflection and Transmission coefficients.
However, I am not sure to setup a plane wave travelling in x-direction. I used exp(-i*k*x) in port settings and chose E-field as input.
I have used a rectangular geometry and setup a port. But I am getting a Gaussian wave rather than a plane wave.
Help would be much appreciated.
Regards
