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 کاملAccurate Modeling of Monopole Antennas in Shielded Enclosures with Apertures
Monopole antennas are usually used for measurement of the shielding effectiveness of metallic enclosures. This paper presents an accurate numerical modeling for monopole antennas attached in shielded enclosures with apertures. The electric field integral equation (EFIE) is formulated for the induced currents on both the monopoles and enclosure. The precorrected-FFT accelerated method of moments...
