Antenna Placement Optimization on Large, Airborne, Naval Platforms Navy SBIR FY2010.1 Sol No.: Navy SBIR FY2010.1 Topic No.: N101-022 Topic Title: Antenna Placement Optimization on Large, Airborne, Naval Platforms Proposal No.: N101-022-1297 Firm: Applied EM Inc. 144 Research Drive Hampton, Virginia 23666 Contact: Phone: (757) 224-2035 Web Site: www.appliedem.com Abstract: Antenna placement on electrically large aircraft bodies is becoming a critical issue. Use of full-wave solvers to assess the on-platform performance of an antenna or the interaction between two antennas is impractical, both in terms of computing resources required and length of execution time. The next best choice is to use a high-frequency code. To address this issue, Applied EM is developing state of the art UTD (Uniform Theory of Diffraction) code for faceted CAD geometries. Although not as accurate as full-wave codes, high-frequency codes require modest computer resources and are faster than full-wave codes. In a serial mode, however, even these codes can take substantial time to execute depending on platform size and complexity. During this SBIR, Applied EM and its team members are proposing porting of already developed UTD code to both CPU and GPU-based parallel environments for the purpose of greatly accelerating the performance. We will identify bottlenecks in current algorithms and target them for posting during Phase I. We will also identify existing algorithms that may be problematic in transferring to a parallel environment and suggest modifications. During Phase II, we plan to develop a commercial grade GPU based UTD code that will be commercialized. Benefits: Given that use of antennas and sensors is expected to continue to grow, the need for electromagnetic simulation tools will also continue to grow. The proposed design software is therefore expected to play a major role in the design and improvement of antennas for a multitude of military and commercial communication systems. Use of such math-based tools will substantially shorten the design cycle and can lead to many dB in improved performance for antenna systems and circuit matching networks. Return
