EMAG TECHNOLOGIES INC. — Department of Defense SBIR Phase II: In this SBIR project, we propose to extend the method of numerically constructed character

Description

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.
