EM analysis and numerical characterization of gaskets: applying a sub-domains decomposition technique

A relevant parameter characterizing a gasket is determined from the measurement of the coupling function between two wires. After applying the reciprocity theorem and making a few hypotheses, the parameter is found as a normalized surface impedance. Its viability is verified, by introducing it in a numerical code based on the electric field integral equation (EFIE). To improve the results, a numerical reciprocity technique is used. In order to carry out an efficient parametric study, a sub-domains decomposition technique is used.
