Hao Xin joined University of Arizona since August 2005 as an assistant professor. He received his Ph.D in Physics under Prof. Mildred Dresselhaus from MassachusettsInstitute of Technology in February 2001. From 2000 to 2003, he was a research scientist with the Rockwell Scientific Company.
He was a Sr. Principle Multidisciplinary Engineer with Raytheon Company from 2003 to 2005. His primary research interests are in the area of microwave / millimeter wave / THz devices, circuits, antennas and their applications in wireless communication and sensing systems. His recent research activities have covered a broad range of high frequency technologies, including applications of new technologies and materials in microwave and millimeter wave circuits such as electromagnetic band gap crystals and other meta‐materials, carbon nano‐tubes devices, solid state devices and circuits, active or semi‐active antennas, and passive circuits. He has authored over 90 referred publications and 13 patents (12 issued and 1 pending) in the areas of microwave and millimeter‐wave technologies, random power harvesting based on ferro‐fluidic nano‐particles and carbon nanotube based devices. He is a senior member of IEEE and chair of the joint chapter of IEEE AP/MTT/EMC/COMM in Tucson AZ.
