Advancing Technologies Through Electromagnetic–Plasma Interactions

The Adaptive Radiofrequency and Plasma Laboratory (ARPL) at The University of Toledo studies how electromagnetic waves interact with plasmas. We use plasma’s tunable properties to develop reconfigurable antennas, tunable RF circuits, and high-power microwave devices. We also use high-Q microwave resonators to realize energy-efficient plasma generators.

Our experiments turn these ideas into working devices, from plasma-enabled electrically small antennas and frequency-selective plasma limiters to low-power plasma sources, atmospheric plasma jets, and long plasma lines. Our work advances these technologies for communications, sensing, and defense and explores applications in high-power microwaves, biomedicine, materials processing, particle acceleration, environmental remediation, electric propulsion, and agriculture.
