Constraint propagation through electromagnetic interaction topologies

The effects of electromagnetic interactions in electrical systems are of concern because of the increased pollution of the environment with electromagnetic emissions and because of the increasing susceptibility of system components. The term electrical system is used herein in the general sense to include more than just networks of electronic components. Systems containing biological and/or mechanical components of varying complexity are also included when reference to the term electrical systems is made. Electromagnetic emissions from components within the electrical system, and also disturbances originating external to it, can be classified as deriving from intentional as well as non-intentional sources. The interaction effects on the susceptible components within these systems range from minor to catastrophic; they cannot always be predicted nor are they always understood. Study and control of this problem is very desirable and has involved the efforts of many persons from varying fields.
