Numerical investigation of the induced voltage on a cable placed at random locations inside a metallic enclosure
2008
In this paper, we investigate the induced voltage on a cable when placed at random locations inside a metallic enclosure. The analysis consists of a cable of defined length and fixed terminals, but different layouts, placed in a metallic enclosure containing an aperture. The induced voltages for the different layouts are computed for a plane wave incident on the aperture. A second analysis is performed with no cable (i.e., an empty enclosure) and the results are compared to those for the cable present. The results are compared to the resonance frequencies of the closed cavity and the aperture.
Efficient Low-Frequency Modal Analysis of Anechoic Chamber
2007
An efficient method to analyze the electromagnetic field inside rectangular anechoic and semianechoic chambers from 30 to 100 MHz is shown. A modal expansion is employed to develop the homogeneous and the inhomogeneous field. This is combined with circuital techniques to compute the effect of the layers of ferrite and dielectrics in the walls of the chamber. Several numerical results of the Free Space Transmission Loss (FSTL) of an anechoic chamber and the Normalized Site Attenuation (NSA) of a semianechoic chamber are provided.
2-D approach to the analysis of semianechoic chambers using a hybrid technique
2003
Semianechoic chambers are the most widely used emplacements for electromagnetic compatibility (EMC) tests. In this work a new and efficient technique for the analysis of 2-D simplified model of a chamber with arbitrary absorber is introduced and validated Some advanced results are presented, and a 2-D figure of merit for studying the overall behaviour of the chamber is proposed.
