Numerical Thermal Dosimetry in Human Head based on TLM method

To control the temperature rise in biological tissues exposed to the electromagnetic waves, the thermal aspect must be taken into account by solving the bio-heat 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.
