Electromagnetic thruster based on circular polarization distribution and cavity of electromagnetic thruster

Abstract

The invention discloses an electromagnetic thruster based on circular polarization distribution and a cavity of the electromagnetic thruster. The cavity is a microwave resonant cavity, electromagneticfield distribution of the resonant cavity has the circular polarization characteristic, and under a Cartesian right-angled coordinate system, the section of the microwave resonant cavity is defined to be in a circular shape; an X axis and a Y axis are located in the plane where the section is located, the X axis and the Y axis are orthogonal, and a Z axis is determined through a right hand rule;and an origin O is at the center of the circular section, an electromagnetic field is distributed unevenly in at least one of the X-axis, Y-axis and Z-axis directions. The cavity is provided with twoor more coupling ports; and the resonant cavity having the circular polarization characteristic is applied to the field of electromagnetic thrusters for the first time, the effect that at present, thethruster works stably is achieved, by introducing the design of the circular polarization electromagnetic field, the electromagnetic field resonance mode can be effectively controlled, and the stability of thrust is improved.
