RF Coil Design
Posted: 14 Jul 2021, 00:09
Hey all, I'm a student working on designing and building RF coils for MRI. I know Elmer doesn't have a dedicated RF module, but I am hoping between the circuit and EM solvers I can put something together. I have previously built this basic surface coil in the CST student suite:
CST is obviously great for this kind of stuff, but the student package is majorly limited and I wouldn't be able to build a larger model, so I was looking at Elmer. I've been reading through the documentation and am trying to figure out how I would build a coil like the one above as a sort of first test/comparison. All the blue lumped elements in this are capacitors, while the red port is a 1V source which I can excite with different frequencies with the goal of finding the magnetic field and S-parameters of the coil. My question is, does anyone know how to connect different pieces of geometry with circuit elements, or could anyone direct me to a resource/specific subset of the documentation where there is more information on how to do this?
