The Role of High Fidelity Geometry Import in RF Modeling

This paper explores several important issues related to the use of high-fidelity computer aided design (CAD) models as the basis for RF model geometries. Leveraging the tools and expertise of the mechanical design community allows for the creation of accurate physical geometry and removes the tedious burden of manually creating the same representation with a computational electromagnetic (CEM) software product. This in turn minimizes geometric simplification as a source of model error and increases the throughput of the RF analysis community. Several critical features of the CAD geometry creation process directly impact the performance and accuracy of subsequent RF models. These include the geometry creation technique, the difference between mechanical and model tolerances, and the design for reconfigurable modeling.
