Applied electromagnetics, microwave and terahertz measurements, nanoscale structures and devices.
Dr. Wong has conducted research in microwave measurement of material properties, dispersive transport in ionic conductors such as solid electrolytes and conductive polymers, transient electromagnetics, wave propagation effects on microwave devices and integrated circuits, millimeter-wave communication systems, and nonlinear device measurement. In collaboration with national laboratories, he has contributed to the development of dielectric-loaded particle accelerators, nanoscale position sensors, and coupler design for superconducting cavity resonators.
Current research efforts include charge interactions in nanoparticles, electromagnetic fields in mesoscopic systems, semi-open structures for material measurements, broadband communication systems, and dielectric-loaded structures for accelerator applications.
