Finite Element Analysis of EMI in a Multi-Conductor Connector

<p>This thesis discusses the numerical analysis of electrical multi-conductor connectors intended for operation at high frequencies. The analysis is based on a Finite Element Tool and looks at the effect of conductors on each other with a view to design for electromagnetic compatibility of connectors. When there is an electrically excited conductor in a medium, it acts as an antenna at high frequencies and radiates electromagnetic power. If there are any conductors in its vicinity they too act as antennas and receive a part of the EM power. Electromagnetic Interference (EMI) from nearby excited conductors causes induced currents according to Faraday's law which is considered as noise for other conductors. This noise is affected by factors such as distance between the conductors, strength and frequency of currents, permittivity, permeability and conductivity of the medium between the conductors. </p><p>To reduce the effects of EMI in a shielded multi-conductor connector, values of induced currents at various distances between the conductors have been calculated and analyzed. The currents have been calculated at high excitation frequencies varying from 0.2GHZ to 1GHZ and distances between the conductors varying from 0.2 mm to 0.8 mm.</p>
