Shaped Radome and Embedded Frequency Selective Surface Modeling for Large-Scale Platforms

The primary thrust of this SBIR effort is to develop and deliver to NAVAIR a complete physics-based computational electromagnetics environment to perform broadband coupling of many antennas mounted on a full-scale platform. Some of the requirements are:•     The method is contributing to new ideas and innovations in computational electromagnetics (CEM), especially in the area of volumetric Boundary Integral Equation (BIE) solvers,•     Demonstrate high order accuracy and an order of magnitude reduction in computational resource requirements over the current CEM state of the art and state of practice, •     Be able to handle different CAD models (IGES, STEP, Parasolid, STL, and SAT) for both the platform and the radome, including several antennas mounted on the platform,•     Be able to handle antenna/radome/structure interaction problem sizes of 1000 wavelengths or more for full scale targets and for installed antenna frequencies to Ku band (12-18 GHz),•     Software architecture to include both CPU and GPU clusters of moderate size (up to 2000 cores).
