摘 要:
分析了矩形谐振腔中快回旋电子束波共振吸收微波能量的物理机理，编制了跟踪单个电子、用4阶精度龙格-库塔法求解的半自洽程序，并据此计算了微波整流器谐振腔部分的转换效率η和谐振腔输出端电子束动能的离散性。结果表明，当共振条件wc=w满足时，电子束非常有效地吸收微波能量，η≈99％；如果要求电子输出动能的离散性小于3％，则电子束的半径应不超过5mm。[著者文摘]

Abstract:
In the paper is analyzed mechanism to absorb microwave energy by fast cyclotron electron beam wave in rectangular resonator of microwave rectifier for microwave power engineering, is developed a semi-consistent computer simulation program in which is used Rung-Kutta method with 4-order accuracy, and is calculated efficiency η from microwave energy to kinetic energy of electron beam. η≈99% is shown if cyclotron resonance wc = w is satisfied,and radius of electron beam must be less than 5mm in order to obtain large total efficiency from microwave energy to d. c. output.[著者文摘]
