Research Institution
In this SBIR project, we propose to extend the method of numerically constructed characteristic basis functions (NCCBF) that was developed under a pervious NAVSEA-funded SBIR for the modeling of coupling effects in large phased arrays. This efficient matrix compression technique will be extended to the fully 3-D case involving both periodic and aperiodic substructures. This extension will allow for the modeling of coupling between arrays of non-commensurate periodicities and their surrounding objects. By extending to mixed periodic-aperiodic substructures, we will be able to use the NCCBF technique to efficiently model antenna-platform interactions as well. Asymptotic solvers will also be integrated within the software to handle very large-scale modeling problems. All the resulting algorithms will be fully integrated within the EM.CUBE framework, which is capable of handling STEP, IGES, OpenFlight and many other CAD formats.
