Dr. James G. Maloney, PhD, MBA
Principal Engineer & Technical Director
Inventor of the Fragmented Aperture Antenna (US Patents 6,323,809, 11,228,102 & 11,937,270) and a recognized leader in computational electromagnetics and antenna design. His career spans over 25 years across academia, defense, intelligence, and commercial industry — including serving as Chief Scientist at Georgia Tech Research Institute, co-founding the engineering practice at Compass Technology Group, and leading the modeling team at PhotonEx Corporation.
Dr. Maloney's FDTD codes evolved into general-purpose electromagnetic analysis tools used extensively across the defense community. He is a two-time IEEE Antennas and Propagation Society Best Paper Award recipient, holder of multiple patents, and is currently authoring the definitive book on Fragmented Aperture Antennas.
