A Plasma Matching Technique for Wideband Electrically Small Antennas
Project ID: TECH-2024-29 Background The demand for wideband electrically small antennas (ESAs) is rapidly growing because of (1) the need for compact multi-functional devices and (2) the limited space available in many applications, especially over low radio-frequency range. However, ESAs are narrowband, non-efficient, and very difficult to be matched,...

High-Efficiency Microwave Plasma Jet
­Project ID: D2021-25 Background Plasma jets are currently made with bulky and expensive equipment that consumes a lot of energy. Most commercially available plasma jets utilize high-voltage pulses (e.g., 100s of V to kV) or high-power radio frequency (RF) sources (e.g., 10s of W), even though low-power plasma with effective surface power density...
