摘要：

Here a new scheme for mode filtering is proposed. Based on the ponderomotive force effect, propagation of the microwave dual-mode through a plasma-filled metallic rectangular waveguide is investigated. To excite the TE20 mode in a rectangular waveguide, the existence of fundamental modes is unavoidable. To filter the destructive mode (TE10), the waveguide is filled with a collisional plasma. Based on the coupling effect, the energy of this destructive TE10 mode is transferred to the TE20 mode. The proposed structure acts like a mode convertor. The TE10 mode become more attenuated and instead the TE20 mode is amplified. The plasma filled rectangular waveguide acts as a mode filtering tool.
