Abstract

The invention belongs to the technical field of strong electromagnetic pulse transmission and transmission and particularly relates to a circular waveguide TM01-polarization adjustable TE11 mode converter. According to the circular waveguide TM01-polarization adjustable TE11 mode converter, a circular waveguide port of a circular waveguide four-way rectangular waveguide is an input port, an inputmode is TM01 mode, a circular waveguide of a four-way rectangular waveguide closed circle waveguide is an output port, and an output mode is a horizontally polarized, vertically polarized or circularly polarized TE11 mode. According to the mode converter, the mode conversion of the circular waveguide from the TM01 mode to the TE11 mode is achieved, the horizontally polarized, vertically polarizedor circularly polarized TE11 mode can be achieved by adjusting the phase of a high power waveguide adjustable phase shifter in the four-way rectangular waveguide, which means that the conversion of the circular waveguide from the TM01 mode to three polarization mode TE11 modes is achieved by one mode converter, and convenience is brought to a strong electromagnetic pulse radiation field for generating the three polarization modes.

Description

technical field [0001] The invention belongs to the technical field of strong electromagnetic pulse transmission and emission, and specifically relates to a circular waveguide TM 01 - Polarization adjustable TE 11 mode converter. Background technique [0002] When the strong electromagnetic pulse is transmitted, it is often necessary to use different forms of waveguides and perform corresponding mode conversion according to the actual application requirements. In the field of strong electromagnetic pulses, the circular waveguide transmission mode is usually rotationally symmetric modeTM 0n modulus, while the most common is the TM 01 mold. If these modes radiate directly, they have deficiencies such as non-concentrated beams, energy dispersion, and low gain. Therefore, it is necessary to convert these modes into modes with more concentrated energy and strong directivity such as TE 11 mode, and then radiate through the antenna. Therefore, researchers at home and abroad h...
