    :  Advanced Materials and Components Research for THZ Application

报 告 人: Dr.  Hao  Xin

           (Electrical  and  Computer  Engineering, 

and Physics at  the University of Arizona)

时  间: 2011731(周日)上午10:00-1130

地  点: 东南大学(四牌楼)李文正楼6614会议室

主  办: 东南大学毫米波国家重点实验室

         IEEE AP-MTT-EMC Joint Nanjing Chapter




Research involving Terahertz (THz) spectrum spanning from 100 GHz to 10 THz has enjoyed dramatic growth in terms of technical achievement as well as commercial implementation recently. The growth is application driven with interests from broad fields such as medical and biological imaging and analysis, defense and security screening, communication networks and radars, etc. Together with a perspective of THz backgrounds, this presentation will highlight several research projects being carried out at Prof. Xin's group. Firstly, THz electromagnetic crystal (EMXT) structures with their design, fabrication, and characterization will be discussed. Demonstration of EMXT based novel waveguides, antennas and other components will be presented. In addition, our  recent development of a  rapid prototyping  technique for mmW / THz component fabrication using polymer jetting will be described.  The great flexibility and potential of this novel fabrication  method will be highlighted.  Our ultimate goal of achieving low-cost, high performance and fully packaged THz  integrated micro-systems will be discussed. Finally, study on carbon  based  nano materials  and  devices  for  high  frequency (microwave to THz) applications will be presented.


Dr.  Hao  Xin,  Associate  Professor  of  Electrical  and  Computer  Engineering, and Physics at the University of Arizona.  He  joined University of Arizona  since August 2005 as an assistant professor. He received his Ph.D in Physics from Massachusetts Institute 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 120 referred publications and 14 patents (12  issued  and  2  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. hxin@ece.arizona.edu 520-626-6941.
