Inductive Electromagnetic Coupling Mechanism and Influential Factors

Abstract

General approaches to electromagnetic disturbances coupling paths talk too little about the condition they occur and about the dimensions of their effects. With the objective to highlight the inductive electromagnetic coupling mechanism, using a simple conductive rectangular loop placed in the vicinity of a straight conductor crossed by a periodical current with sinusoidal and trapezoidal waveform, and by solving the equivalent circuits in the sinusoidal regime and the corresponding differential equations for the trapezoidal waveform of electric current pulses, the electrical quantities and the influence of extrinsic factors were obtained. This paper is a concrete, precise, simple, and clear approach that establish theoretical base of some useful large scale applications like high frequency shielding.
