Outlines of current research
At the University of Electro-Communications, he has established ultra-high efficiency class-F and class-R GaN HEMT amplifier design method, where more than 4th order higher harmonic frequencies can be taken into account under the existence of parasitic reactive elements. Also he has developed ultra-broadband active and passive components for UWB applications such as planar self-complementary antennas, HBT MMIC amplifiers with active balun, broad-side coupled four-line band pass filters with designed frequency notch. He has also been developing a co-simulation technique of electromagnetism and semiconductor device physics for microwave/millimeter wave devices and high-efficiency microwave rectifiers as a time reversed dual of high-efficiency power amplifiers.
