RF Power Measurement & Control

This project focuses on the advancement of RF power measurement and control techniques, led by Richard Ooi and Luke Nemuras under the guidance of Dr. Collins. Key objectives include optimizing plasma characteristic measurements—such as heat, voltage, and impedance—while ensuring portability and stability. Applications span surgical plasma, surface decontamination, and water purification. The project's ethical considerations address safety related to UV and electromagnetic waves. Current advancements involve programming the Cypress PSoC microcontroller and improving design elements for Engineering Day.
