Problem in adding source in electromagnetic wave time domain

Please login with a confirmed email address before reporting spam

Hi, I want to simulate a 2D GPR case in time domain with RF module ewte. The model has two layers of air and earth. I need to put a point source at the air-earth interface. But the point can't be selected in the physics field. And the boundary field can only be added to the outer boundary. So how should I add a point electric or magnetic source to the inner interface?
