RF MODULE

solutions for both the electromagnetic problem and the heat transfer problem in
parallel. This takes into account the coupling of the resistive heating from the
electromagnetic solution into the bioheat equation. In principle, however, you could
solve the two problems in sequence because there is only a 1-way coupling from the
electromagnetic problem to the bioheat problem.
