Research Institution
In this Phase II Small Business Innovation Research project, we propose to develop a software tool for the modeling of radiation, scattering and coupling of large phased arrays. The available full-wave simulation techniques require enormous computationtime and memory usage when treating large finite-size arrays, while infinite periodic simulators cannot predict the coupling and edge effects accurately. For this project, the object-oriented foundation of EMPiCASSO, an existing antenna design CADsoftware, will be used and enhanced with a novel decompose-solve-recompose (DSR) technique. The proposed technique decomposes the large phased array into smaller segments including inner and outer (edge) subarrays, solves for them separately and recomposesthem again for the final solution. The code implementation will further be parallelized for the DoD?s high performance computing platforms. The proposed software tool will be used for the design of phased arrays and large-scale antenna systems. Thesetypes of antennas have a variety of applications in both military and civilian communications and sensing systems.
