TLM computation of temperature distribution in human head exposed to electromagnetic waves

To simulate the temperature elevation in biological tissues exposed to the electromagnetic waves, the thermal aspect must be taken into account by solving the bioheat equation. In this paper, a new numerical scheme based on the TLM method, particularly suitable to highly heterogeneous environments, is applied for computing thermal distribution in a human head exposed to plane wave at 900 MHz. The model was proven to be unconditionally stable which allows using a larger time step than the one involved with FDTD or other TLM models. The numerical results are compared with those simulated with CST.
