摘要
As the second order finite difference expressions discretize the spatial derivatives in heat equation accurately only for the homogenous material model with constant thermal conductivity, we proposed a method to numerically determinate 3-dimensional thermal response due to electromagn etic exposure accurately even for inhomogenous model. In this paper, the 3-dimensional (3D) EM-thermal modelling is performed with finite volume method. High numerical accuracy of the proposed method allow in vitro experiments with inhomogeneous tissues and non-uniform meshes. The validity of the method is demonstrated by comparing results with the fraction-step semi-implicit method.
