摘要
电磁导弹一直是作为Maxwell方程的渐近解来研究的,它是否可以严格分析还不得而知。本文根据辐射源的电流分布,仅用矢量位A表述电磁场,给出电磁导弹辐射线上的严格场解,包括电场、磁场和能量的频域解与时域解,为严格分析任意激励波形的传播特性和理解电磁导弹的慢衰减机理提供了数学基础。
Electromagnetic missiles have been ever investigated in terms of approximation solution of Maxwell equation.It is doubtful whether this problem can be analyzed strictly.According to current distribution of radiation source,only using vector potential A to denote electromagnetic field,this paper presents the strict solution for electromagnetic missiles.It lays the mathematical foundation for analyzing propagation properties of arbitrary excitation waveforms and understanding slow attenuation mechanism of electromagnetic missiles.
