均匀半空间回线源非中心点频率域电磁场计算
A new calculation method for double bessel function integration
摘要
Abstract
According to the double Bessel function integration account in the process of calculation non-center point transi-ent electromagnetic field,a new numerical method based on Biot Savart Law was offered in this paper.We describe the field as the summation of primary field stimulate by the loop and secondary field generated by the media,after analysis the pattern of the kernel function,calculated the two integral function with respective method.In order to confirm the validity,subdivision the loop into some electric dipole,comparing the result acquire by superposition every electric dipole to that gain from the meth-od offered,it prove the effectiveness of the new method.关键词
