| 摘 要： | 提出了一种适合于人体感应加热时多层媒质的三维涡流场的数值计算方法，并用互补变分法、数值解法求出的磁场强度来计算涡流的分布。为验证这种方法，计算了一个放在均匀交变磁场中的导体球的磁场和涡流，结果与理论值相符。用这种方法对人体内涡流进行计算，得出了人体模型内功率密度的分布情况。

| Abstract: | In this paper, a numerical method of calculating the multimedia 3D electromagnetic field in the human body under hyperthermia is presented. The complementary variational method is used to solve the induced eddy current. The numerical result is compared with the theoretical result of a conducting sphere in a uniform magnetic field. Spatial distributions of the induced eddy current and power are obtained in a human model. |
