Hybridized Full Wave ? Asymptotic Electromagnetic (EM) Computational Engine for Antenna Computer Aided Design (CAD)

The objective of this Small Business Innovation Research (SBIR) project is to develop accurate and computationally efficient scalable algorithms that can be used to characterize the performance of antennas and array systems built on complex vehicleplatforms. By accurate modeling of antenna-platform interactions, these effects can be taken into account during the antenna design process. Such virtual prototyping can save time and cost during the design cycle. For the Phase I feasibility study, it isproposed to interface a full-wave finite element simulator with high frequency asymptotic techniques such the shooting and bouncing rays (SBR) method. The resulting code will be validated with results from a complete full-wave solution run on highperformance computing (HPC) platforms. A visual software environment with design utilities will be developed to facilitate the usage of the code. The CAD tool resulting from this SBIR project will be able to save time and cost for military and commercialantenna designers. It will help achieve better antenna designs by taking the platform effects into account.
