Computer simulation on nonlinear interaction of intense microwave with space plasmas

The concept of a solar power station (SPS) was proposed 25 years ago. During the intervening years, long-distance, high-power transmission microwave technology has advanced. Realization of wireless power transmission in space is now no longer a dream. It has been predicted from three-way coupling that a static plasma wave is excited when an intense microwave passes through space plasma. The microwave power transmission rocket experiment in an ionosphere carried out by the authors (MINIX, Microwave Ionosphere Nonlinear Interaction eXperiment) has confirmed this fact. In this experiment, a phenomenon that cannot be explained by the three wave resonance theory has been discovered. In this paper, a computer experiment using plasma has been carried our with an electromagnetic particle code. Static plasma wave excitation and the saturation phenomenon are explained in which not only the simple three-wave coupling but also the wave-particle interaction are included.
