Harmonic generation of high power microwave in plasma filled waveguide

采用等离子体流体理论,研究了高功率微波在等离子体填充波导中的谐波产生,导出了非线性波动方程.对二次谐波产生进行了数值计算与分析.理论分析和数值计算表明,高功率微波将在等离子体填充波导中激发起谐波,TE0n模式与TM0n模式的基波都将激发起TM类型的谐波.

We adopted plasma fluid theory to analyze the harmonic generation of high power microwave in plasma filled waveguide, and the analytical theory is presented. The numerical calculation and analysis of second-order harmonic were also done in this paper. The theoretical and numerical analysis showed that high power microwave can generate harmonics in the plasma filled waveguide, and wave of both TE0n mode and TM0n mode can excite harmonics as TM mode.
