# Davis Advanced RF Technologies Lab

### Welcome to the Davis Advanced RF Technologies (DART) lab

We are a group of researchers with a keen interest in many exciting areas of high frequency electronics. Our research interests include:

• Reconfigurable high frequency devices and components;
• High frequency integrated circuits;
• High frequency communication and radar systems and their application in biomedical, societal, and environmental applications.

Critical to our scientific research efforts is a pursuit of fundamental understanding of the engineering principles of high frequency electronics. A major mission of our work is to formulate and disseminate such understanding through university education as well as community outreach.
