1.引言由于电磁波的生物效应及在医学上的应用,研究电磁波在生物媒质内的传播、引起了人们的注意。目前已知的生物媒质的电参量是不均匀的,具有各向异性,而且随时间而变。生物体的边界形状也不规则,而用寻常规则的圆,矩形、椭圆等形状来逼近处理。若媒质的介电常数为ε,导磁率为μ,电荷体密度为ρ_(?),磁荷体密度为ρ_m,则麦克斯韦
1. INTRODUCTION Due to the biological effect of electromagnetic wave and its application in medicine, it has drawn people’s attention to study the propagation of electromagnetic wave in biological media. The electrical parameters of currently known biological media are non-uniform, anisotropic and change over time. The boundary shape of the organism is also irregular, but the shape of the circle, rectangle, ellipse and so on with the ordinary rules approximates the processing. If the dielectric constant of the medium ε, permeability μ, charge density ρ_ (?), The magnetic charge density ρ_m, Maxwell
