Abstract :
The development of an adaptive surface is presented, which can be switched between a transparent surface and a reflective surface. MEMS-bridges are used as the controlling device. The surface consists of a ground plane with apertures and square ring elements on both sides of the plane. MEMS-bridges can block the apertures for the reflection operation, otherwise the surface will behave as a transparent one. The unit cell study is discussed for the performance of the surface.
