Web1 apr. 2024 · In the engine cycle, microwave beams are injected into the thruster from the open end. The incident beams are then focused by the focusing reflector; plasma is ignited at the focal point. The ionization front of the plasma propagates toward the incident microwave beam, absorbing the beam power. A shock wave is then driven. Web8 jan. 2024 · A microwave–rocket system for rocket launching was proposed as an engineering application using an intense millimeter wave beam. Flight demonstrations and thrust measurements were repeated while changing the ambient pressure, beam power density, beam profile, and vehicle shape.
