Microwave ablation - Electric field computation
Posted: 01 Jun 2021, 23:38
Hi all,
I have been playing with Elmer for a while now and decided to run my on case. I would like to simulate microwave ablation on liver tissue, for biomedical applications. So, basically, as a first step, I would like to compute the damped electric field that a microwave antenna radiates into the tissue.
My model consists in a quarter of the whole problem, due to symmetry. It is basically an antenna (coax cable (dielectric material) that has has a slot close to the end an it is surrounded by a catheter - that is also a dielectric). And this antenna is surrounded by the liver tissue.
I am only using the Vectorial Helmholtz solver, but getting a trivial solution. I wonder what I am doing wrong. If I try to simplify an run only the coax cable (which is basically a waveguide), then everything works okay....
I am attaching .sif file, in case someone have a chance to look at it and help me. I have tried to add my mesh, but file is too large....
Any suggestions is really appreciated!!!
Thanks again!!!
