Numerical Modeling of Complex Electronic Systems

The objective of this effort is to develop strategies for electromagnetic modeling of highly complex systems by using a suite of Computational Electromagnetic (CEM) codes based on a variety of algorithms, and hybridizations thereof. Although a wide arrayof CEM tools are currently available for modeling objects with arbitrary geometries and inhomogeneities, they are typically limited, severely, in the size of the problem they can handle. Furthermore, many of the existing codes do not have an interface thatenables the user to conveniently enter the object geometry using their own CAD tools, and to view the fields and induced currents computed by the code without considerable amount of manipulation of the output data set generated by the modeling code. Giventhis state of the existing CEM codes, we propose to develop novel approaches, described below, that would substantially extend the range of applicability of existing CEM tools and enable them to be scaled to much larger problems. We also propose to developUser interfaces for the codes that would work with existing databases or CAD files for the objects in a convenient manner. Anticipated improvements in the CEM tools would be of immediate use to several other projects of interest to various DoD agencies,especially the Navy, in connection with EMI analysis of proposed or existing designs, for which no accurate tools are currently available.
