Abstract
In this paper, a digital metamaterial of arbitrary base based on liquid crystal (LC) is proposed. The digital metamaterial can be multiplexed for different desirable functions by properly biasing the LC for different code patterns. Simulation results of two common functions, beam steering with a steering elevation angle 27° and RCS reduction of at least 10 dB from 51 to 56 GHz, have been presented to prove the concept. The feasibility has been further confirmed by preliminary measurement.
