Practical and theoretical evaluation of EMC/EMI Problems Of Metallic Enclosures With Apertures
Abstract
In this paper, experimental and theoretical
evaluation of coupling of electromagnetic radiation is
reported. Validation of the results is obtained by
comparing the experimental data with theoretical data
both generated using CONCEPT Simulator and data from
our hybrid MoM/FDTD formulation for the analysis of
metallic enclosure with apertures. Both the CONCEPT
Simulator and the hybrid MoM/FDTD formulation utilize
the method of moments, however, the hybridization of
the latter makes it more adaptive to the solutions of
apertures of arbitrary shape within enclosures with
inhomogeneous dielectrics. The problems analyzed are
rectangular slot, cross-shaped aperture and diamond-
shaped aperture. The experimental results and
MoM/FDTD results also agree fairly well with those
available in the literature.
