Electromagnetic Emission Modeling in Case of Shielded Cabling With Respect to the Ground Dielectric Properties

Abstract

Satellites and spacecraft subsystems in general are vulnerable in terms of electromagnetic interference. Shielded cables, connecting these subsystems as well as the subsystems themselves, are major sources of electromagnetic (EM) emission. The minimization of these emissions is critical in order to achieve EM cleanliness. An accurate model predicting these emissions could offer great insight and enable interference minimization. In this study, a shielded cable model for predicting EM emission via decomposition of contributing phenomena is presented including the ground dielectric properties. The model is built based on a standardized measurement setup and validated for different cases of ground material and cable's position.
