hi fereshteh, please see the attachments. I'd like to simulate a conformal microstrip coil with hfss which resonates at 128MHz for MRI.
It is side fed and tuned and matched with lumped LRCs.
At first, the circuit is short seen from smith chart. I changed the
grid settings and
curved object visualization, elements in the model are mostly created using
sweep and rotate. I have check the model carefully and its runs without warning.
However, it seems that the magnetic field results indicated that little energy had been transmitted into the p@tch, and most aggregated at the excitation part. I have tried meshing the tiny parts in the model but without improvement:???:.
The ideal magnetic field is what look like in the attachment "desired magnetic field".
Could you please help me to see what's wrong with the model? or different model methods?
FYI, the file was created with hfss 13.0, and the dimensions of the p@tch are given for prostate MRI.
