论激励电流的广义函数性质

On extensive function character of drive current

根据电磁场理论,由电子注在波导中的辐射过程,推导出由电流所激励的电磁波的辐射功率等于电流对场所作的功,证明了电子流辐射过程中的能量守恒关系,直接由麦克斯韦方程组推导出微波电子器件理论的解析解。

bstract: According to electromagnetic field theory, through the radiation of electron beam in the wave-guide we derive that the radiant power of electromagnetic wave excited by electric current equals to the work generated by current, and we prove the energy conservation law in the radiation process of electron current. Based on the Maxwell's equations we directly get the analytic solution of the microwave electron theory.
