Microwave rocket is expected to achieve the dramatically low cost way in order to transport mass materials to the space. (e.g. Space Solar Power Satellite). In the previous study, we succeeded in demonstrating 5 m beam transmission. The method is composed of two systems. First, a beam expander composed of a couple of offset parabolic mirrors was applied on the beam transmitter side. Second, the beam was condensed on the vehicle side to provide enough power density to propel the vehicle. However, both of the beam expand and the beam condenser have some problems. One of them is the bad beam profile after the beam expander system. Another is the mirror-exhaust gas interaction at the exit of the thruster, where a pair of offset parabolic mirrors interfered in generating thrust. In addition, the vehicle's center of mass was off axis because of the beam condenser optics. We solved those problems using a phase corrected mirror on the beam transmitter side and a new tapered mirror beam condenser on the vehicle side. These mirror systems were designed using both of the phase correction method and the ray tracing method.
