Abstract :
The frequency responses of coaxial cables employing wire braided shields, excited by external fields, is studied using an algorithm based on a distributed circuit model, which uses both electric and magnetic field parameters to model the external field coupling. The simplicity and fast speed of the model enable computer-aided analysis of externally induced noise in cable interconnects to be carried out in a computationally efficient manner. A general CAD algorithm is developed, based on this model, and it is applied to the study of the response of cables over a ground plane. The algorithm is then used to study the effects of different braid constructions on the responses of cables excited by external fields. Responses of cables with optimum braid designs in their shields are studied in detail. The model uses the experimental values of the leakage parameters which are measured separately using a standard triaxial text fixture
