Welcome to Dr. Heather Song’s Research Group!
UCCS Applied Electromagnetics Laboratory
UCCS Applied Electromagnetics Research Laboratory’s primary focus is on the theoretical and experimental research on the microwave/ millimeter-wave/ terahertz radiation source, interaction between electromagnetic radiation and human body, and advanced antenna research. Recent projects are heavily associated with developing high frequency microwave/ millimeter-wave/ terahertz devices which requires design, construction, and characterization of high power microwave tubes, millimeter-wave vacuum electronic devices, novel electron guns, RF coupling structures, innovative RF circuits, and efficient collectors. Projects involving bio-engineering include terahertz dielectric spectroscopy research for non-invasive cancer screening and detection and work involving cell phone radiation effect on human brain. Various novel antenna concepts for future advanced communication systems are currently under investigation.
