A Modified Hybrid MoM-Modal Method for Shielding Effectiveness Evaluation of Rectangular Enclosures with Multiple Apertures
A new hybrid modal-moment method is proposed to calculate fields penetrated through small apertures on rectangular metallic enclosures. First, the method of moments is used to numerically solve the governing electric field integral equation for the equivalent two-dimensional surface-current distributions on the surface of metallic enclosure including any number of rectangular apertures of arbit...

متن کاملStudy of the Shielding Effectiveness of Double Rectangular Enclosures with Apertures Excited by an Internal Source
An analytical formulation has been developed to evaluate the shielding effectiveness (SE) of two coplanar rectangular metallic enclosures with a circular aperture excited by an internal electric dipole source. The formulation consists of three parts: First, the near-field electromagnetic interference (EMI) of the electromagnetic leakage from the aperture is represented by the electric dipole in...
متن کاملShielding Effectiveness Simulation of Small Perforated Shielding Enclosures Using FEM
Numerical simulation of shielding effectiveness (SE) of a perforated shielding enclosure is carried out, using the finite element method (FEM). Possibilities of model definitions and differences between 2D and 3D models are discussed. An important part of any simulation is verification of the model results—here the simulation result are verified in terms of convergence of the model in dependenc...
متن کاملShielding Effectiveness Measurements on Enclosures with Various Apertures by Both Mode-tuned Reverberation Chamber and Gtem Cell Methodologies
The shielding effectiveness (SE) measurements on enclosures with various apertures by both reverberation chamber (RC) and GTEM cell (GC) methodologies are presented. Furthermore, computer simulation through commercial software (CST) is used to compare with the experimental data. Our results show that the SE of the rectangular enclosure with five different apertures from RC is usually larger tha...
