  • The conception of active reflection was presented. Using th e periodical surface′s character of band gap and impedance transition of electr omagnetic crystal structure such as photonic band gap(PBG), frequency selection surface(FSS), high impedance surface(HIS) and so on, the varactor diode was p ut onto the approximate HIS′s surface to join each cell of metal on top layer t o realize the electronic control for periodical structure. The active periodical structure was eslablished. The propagation characteristic of incident electromagnetic wave was effected and controlling the refle cted phase and direction of reflector electromagnetic wave were realized. The si mulation test proves that this method and technology can control reflector w ave′s phase and direction of on working freque ncy band by using single or double layer active periodical structure effectively .
