ELECTROMAGNETIC RESEARCH SOLVES PROBLEMS FOR AIR FORCE

Dr. Cagatay Tokgoz was recently awarded a Faculty Fellowship from the United States Air Force Research Laboratory (AFRL) where he spent twelve weeks over the summer of 2017 conducting research for antenna placement in aircrafts. Through his fellowship, Dr. Tokgoz developed efficient ray-tracing techniques and electromagnetic solutions then applied them to representative computer models of aircraft platforms to identify co-site interference between antennas on the same platform.

In the area of computational electromagnetics, Dr. Tokgoz is one of a handful of researchers in the United States whose expertise resides in the development and application of efficient numerical techniques and solutions for antenna placement on large structures such as aircrafts. Because of his expertise in this area, Dr. Tokgoz has attracted strong interest from the CREATE-RF, a program funded by the Department of Defense and run through AFRL.

The careful placement becomes extremely crucial for antenna-platform interactions and co-site interference.”

The techniques and solutions developed during the fellowship have been planned to be integrated into the SENTRi software currently being developed by the CREATE-RF team. New capabilities will greatly assist the United States Air Force in finding optimal placement of antennas on airborne platforms of aircraft and missiles to minimize the co-site interference between the two.
