Yes, you can apply surface currents to a perfect conductor in the RF module. Normally, one applies port boundary conditions (there are several types available) when setting up current-driving (or wave-launching) configurations, especially when one is interested in computing reflected and transmitted waves. I encourage you to take a look at some of the examples provided with the applications library for the RF module to learn how this is done and to learn more about the boundary-condition setting tools, and post-processing tools, which are provided to make it easier for you to both set up your problems and analyze the results.

Robert,

Thank you for your response. I wanted to see if you had an example in mind that would work? I couldn't find any that had a great example. Moreover, I wanted to see if i could apply any Amperage to a conductor in the RF module? I wasn't able to tell if i could actually have that type of control. In general, I was trying to send a wave from the top place(to the bottom) of the piece and have a piece that acted like a exposed wire that had 0-15 Amps applied through it(right plane to left plane of the piece) so i can graph the response of 0-15 amps with the transmission and reflection. I thought I had to use the AC/DC module to to get this type of control and get accurate current on the conductor/exposed wire, but I couldn't figure out how to do that either as I am very new to comsol.

Thanks,

The post is more valuable for me.I am very interested in which metterical are better conductors use in insulators. Internet Explorer 10 support
