Dr. Kaveh Delfanazari

Project
Quantum and Superconducting Metamaterials

Short CV
Dr. Delfanazari investigated superconducting terahertz (THz) devices during his Ph.D work at the University of Tsukuba, Japan, where he received the Dean’s Award for Excellence in the Ph.D thesis, and the Japanese Government Scholarship, etc. His research interests lie in the areas of superconducting electronics and photonics including Josephson junctions and SQUIDs, Metamaterials, and Plasmonic Devices.
