New Methods of Constructing Computer Controllable Metamaterial and its Microwave Absorber Application

To put computer controllable metamaterial (CCMM) into practical use, a wiring problem has been a major road block to break through. This problem is resolved by introducing an idea of "false wiring". Microwave absorbers are taken as one CCMM application. The method of theoretical design of the present CCMM is provided by FDTD analysis in the case of including active circuit elements as the first approximation. Good matching characteristics below -30dB at 4.55GHz and 5.25GHz are obtained by controlling 2D and 3D CCMM electrically with only two wirings for feeding a bias voltage to PIN diodes. Consequently, one substrate with 144 wirings could be reduced to only 2
