Innovative improvements to High-Frequency Simulation Methods for Installed Antenna Performance
Delcross proposes to systematically validate the Savant and Savant-Hybrid solvers for a wide variety of problems. When shortcomings in existing methods are identified, they will be investigated and revised as necessary to provide good comparison with benchmark solutions. Our approach will first consider canonical problems involving PEC structures that are well understood. We will use Savant and a full-wave solver to run the canonical test cases and then compare the results. We will then perform validations of the material models in Savant by comparing Savant and full-wave simulations for simple geometries involving single and multi-layer dielectric materials and eventually work up to complex radomes. We will also work with NAVAIR to compare Savant simulations with measured data for an antenna mounted on an aircraft. We will consider additional platforms for which measured data exist and potentially design test cases to be measured in an anechoic chamber or at an outdoor range. We plan to implement advanced physics models in Savant to improve the existing models. Validation of the advanced physics models would occur as part of the proposed effort. Finally, the Savant-Hybrid solver currently under development will be validated through comparisons to measurements and full-wave solutions.
