Currently, he is working on another DARPA-funded program entitled MEMS/NEMS Science and Technology Fundamentals under which he has significantly improved the power-handling capacity of MEMS switches. In addition, he is working on a program funded by the Missile Defense Agency for high-power MEMS phase shifters. Dr. Hwang is the inventor of a metamaterial-based phase shifter with very low loss, excellent impedance match, and constant phase shift across a very wide band. He has also demonstrated closed-loop intelligent CMOS control of MEMS devices that can further improve robustness and reliability.
