摘要: 從狀態(tài)方程出發(fā),通過四度空間的Maxwell方程協(xié)變形式、電磁張量、能量-動量張量在電子注坐標上進行相對論變換,研究了回旋自諧振脈塞的互作用過程,導出了新的互作用狀態(tài)方程。理論上證明了CARM中工作在TEmn模無縱向電場分量情況下電子注交換縱向能量的機制是存在的。Abstract: From phase equation in an electron cyclotron autoresonance maser (CA-RM) amplifier the interaction between beam and electromagnetic waves is investigated with help of four-dimesional Maxwell equations, electromangetic-field tensor, energy-momentum tensor. The new phase equation is transformed by Lorentz transformation. Being non-longitudinal electro-field component, presence of longitudinal energy change between longitudinal moving beam and TE(Hmax) mode is jutified in theory.
