The invention discloses a long-service-life microwave cusped field plasma thruster applying a magnetic shielding technology, relates to a thruster, and provides a design scheme of the long-service-life microwave cusped field plasma thruster aiming at the service life requirement of tens of thousands of hours generally required by current spacecrafts on micro propelling devices. The device comprises a plurality of permanent magnets, an aluminum oxide ceramic channel, a microwave coaxial resonator and a shell, the aluminum oxide ceramic channel is located at the left end in the shell, the microwave coaxial resonator is installed in the shell and located on the right side of the aluminum oxide ceramic channel, and the aluminum oxide ceramic channel is sleeved with the permanent magnets. On the basis of keeping the high performance of the design scheme of the thruster, by introducing the magnetic shielding technology, the degradation process of the thruster is effectively delayed, the service life of the microwave cusped field plasma thruster is greatly prolonged, and the applicability of the microwave cusped field plasma thruster to a space gravitational wave detection task scene is remarkably improved. The invention belongs to the technical field of spaceflight.
