Whole Body SAR Estimation of a Rodent Inside a Reverberation Chamber

Monte-Carlo statistical analysis is combined with finite-difference time-domain (FDTD) electromagnetic simulation to model the absorption of radio-frequency electromagnetic fields by a mouse in a reverberation chamber. The purpose of this paper is twofold: 1) rigorous derivation of the statistics of the N random plane wave model with MATLAB codes for validation, 2) implementation of the N random plane wave model in a commercial FDTD software and estimating the proportionality constant relating the mean whole body specific absorption rate of a OF1 mouse to the mean square electric field. The estimated constant was found to be close to a recently published work.
