Modeling cosine wave from rf coil

Please login with a confirmed email address before reporting spam

Hi, I'm having trouble with modeling a simuation with rf coil. I want to calculate the E-phi change(dependent on time) at the point of the center of the geometry. I've used the "electromagnetic" model builder, and "frequency-domain" solver. There was no big trouble making the geometry I want, but I don't know how to make a wave source of sine and cosine wave. I've used "pointwise constraint" section. Is it right way to set the wave source from the rf coil? How should I set this section to get the sine and cosine waveform? Also, I'm not sure if it's right to use the frequency-domain solver.

Please help me to figure it out, thanks in advance.
