Overview Of Present EMC Analysis/prediction Tools And Future Thrusts Directed At Developing Avexpert Systems

Abstract

This paper provides a brief overview of major EMC analysis and prediction codes that are presently available and in wide use. In particular, this paper highlights the capabilities of the latest versions of the lntrasystem Electromagnetic Compatibility Analysis Program (IEMCAP) and the General Electroma netic Model for the Analysis of Complex Systems (GEMACSqcodes. First, the analysis methodolog and general concepts for applying sophisticatec!tools like IEMCAP and GEMACS to complex systems that incorporate many electroma netic are overviewed. Since IEMCAP represents a class of widely used EMC tools and since it can address a relatively wide range of EMC problem solving concernsfor complex systems, it is emphasized throughout the discussions. In particular, IEMCAP's software structure, basic input data parameters list, built-in engineering models, and stored EMC limits which are in accordance with MIL-STD-461 and MIL-E-6051, will be overviewed. Also summarized in this paper are several important thrusts directed at advancing the state-of-the-art in computational electromagnetics software using artificial intelligence/expert system (AI/ES) technologies. transceivers (i.e., boxes, antennas, wire/ca % le bundles, etc.)
