High Fidelity EM Design, Prediction and Optimization of Airborne Radomes

Performing accurate simulations of large- and multi-scale electromagnetics problems, such as complex radome-antenna and antenna-platform interactions, has far-reaching implications for NAVAIR. Simulation problems involve complex materials, multiple feeds and loads, and geometries that may exceed 1000 wavelengths in one or more dimensions while critical geometry features are less than 1/100th of a wavelength (i.e., the multi-scale geometry problem).  IERUS Technologies proposes a radical departure from the standard workflow for antenna-radome system analysis and optimization: direct CAD/CEM integration via spline-based simulation (SBS).  This approach will eliminate typical multi-scale meshing issues, provide for intrinsic high order (HO) meshing and solution accuracy, and provide a platform for a next-generation user experience for CEM modeling and design (see Figure 1).  Through this work, we will break the 40-year-old cycle of EM CAD preparation, long meshing times, and long run times.  With this new SBS-enabled V-Lox the exact geometric description is embedded in the analysis and can achieve arbitrarily high-order accuracy solutions.
