Research

Dr. Torrico’s current research topics include wave propagation in random media, radiation and scattering, wave propagation in natural and vegetated urban environments applied to cellular and related applications, wave propagation in confined environments, and spectrum management techniques. Also, Dr. Torrico (1985-Present) is presently Principal Scientist at Comsearch, an Andrew Company, in Ashburn, VA, where he has been responsible for directing Comsearch’s efforts in research and development in the areas of radiowave propagation and system design pertinent to mobile communications systems, terrestrial microwave communications systems, and mobile satellite systems. He is the co-author of a chapter for the Handbook on Antennas in Wireless Communications (CRC Press – 2002).
