英文摘要：

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.
