When implementing wireless power transmission systems in society, two important issues need to be considered. One is that it can coexist with existing communication systems, another is to minimize the impact on humans and animals. For the first task, the author proposed the use of a two-sided retrodirective system. This is because radio wave leakage is minimized and interference with the communication system can be expected to be avoided. In order to solve the latter problem, it is necessary to develop a technology in which a power transmission beam can instantaneously avoid an intruder when a person or an animal accidentally enters the beam. The authors accidentally discovered that a two-sided retrodirective scheme that solves the first problem also solves the latter problem at the same time. Here the behavior of the beam to avoid the radio wave absorber in the transmission space is described.
