Tunable Negative Refractive Index Metamaterials and Applications at X and Q-bands

Abstract

The goal of the current DARPA-ARO funded project is to design, fabricate, and test a tunable negative index metamterial (TNIM) using ferrites as a constituents material in the frequency range of 36-44 GHz with a targeted center frequency of 50 GHz. During this one year program we successfully accomplished tasks and continued our effort in developing a Q band tunable phase shifter and X band TNIM technology for microwave integrated circuits. This additional effort has lead to the development of microstrip TNIM and a phase shifter in a microstrip form working in X band. The Q band waveguide TNIM and X band microstrip TNIM phase shifters are the first device applications of the ferrite based TNIM. We have demonstrated excellent tunability of both the phase shifters by the application of external magnetic field.
