Research Interests in Our Group
Our research group seeks to develop new directions in classical areas of electromagnetics and RF/microwave engineering, but is centered around the study of 'metamaterial' technologies. Metamaterials are artificial materials designed to possess exotic electromagnetic properties not available in nature, such as a negative refractive index. Their unusual properties can be leveraged to improve the performance of several devices and, sometimes, yield entirely new phenomena. Metamaterials represent an explosive emerging research area that has attracted significant attention in recent years for groundbreaking innovations. Our research group is investigating the ways in which we can control electromagnetic fields using such metamaterials, as well as their applications to practical devices and components for biomedicine, defense, and telecommunications. Some examples of our group's most recent contributions are listed below.
