Hello,
i'm doing some rf coil, with tuning capacitors, simulations using HFSS. The impedance bandwidth is very very narrow (S11), which is expected. I found that when i changed some minor values in the simulations, say just move the coil to the left or right by delta or increased the air-box size a little, the s11 curve chaged a lot!! It means that the HFSS doens't help in my case, . Actually, i'm looking for a simulations software that's good for RF coil design, coil array designs, coil to coil isolations, for MRI applications! Does anyone have any suggestions on good simulations software for MRI applications?
Please help
I didn't find the right solution from the internet.
