My model is using CYLINDRICAL coordinates, and I need to make a circularly polarized source to feed into one end of my cylindrical waveguide. I found this comment from Steven Johnson back in 2008:
> A circularly polarized planewave in cylindrical coordinates is E = > (rhat + i phihat) exp(i phi). So, just create a constant Er (radial) > current source and a constant Ep (phi) current source with amplitude > 0+1i, and use m=1. But I am unclear on how to actually do this. It looks like I need to put two (make source) objects on the sources list, one with an Er component and one Ep, But is the amplitude part simply (amplitude 0+1i) for both of them? No amp-func required? Where does the "m" go? I have been unable to find any examples for how to do this. Perhaps a 'planewave' is not what I am looking for anyway...
