Abstract

A knowledge-based approach for the modeling of electromagnetic (EM) interactions in a system is described. The purpose is to determine any unwanted EM effects that could jeopardize the safety and operation of the system. Modeling the interactions in a system requires the examination of the compounded and propagated effects of the EM fields. A useful EM modeling approach is one that is incremental and constraint-based. The approach taken here subdivides the modeling task into two parts: (a) the definition of the related EM topology and (b) the propagation of the EM constraints. A prototype of some of the EM constraints has been implemented in Quintus Prolog under NeWS on a Sun workstation. User interaction is through a topology drawing tool and a stack-based attribute interface similar to the HyperCard interface of the Apple Macintosh computer
