Shielding Effectiveness of a Lossy Metallic Enclosure
In this paper, shielding effectiveness (SE) of a perforated enclosure with imperfectly conducting walls is evaluated. To this end, first, an accurate numerical technique based on method of Moments (MoM) ispresented. In this method, lossy metallic walls of the enclosure are replaced by equivalent electric surfacecurrent sources. Then, the impedance boundary condition on the imperfectly conductin...
متن کاملTransmission Line Model for Shielding Effectiveness Estimation of a Rectangular Enclosure with Apertures
In this paper, an approach to the shielding effectiveness evaluation of a metallic enclosure with apertures is discussed. It has been previously shown that a simple analytical transmission line formulation gives good predictions of the shielding effectiveness of a metallic enclosure with apertures. In this work the model is extended to include the fundamental formulas to deal with the cases of ...
متن کاملElectromagnetic Pulse Coupling inside a Rectangular Enclosure with an Aperture
The transmission line matrix time domain (TLM-TD) method is used to simulate the electromagnetic pulse (EMP) coupled inside a shielding box with an aperture. Simulations for different electromagnetic pulses regarding to different rise time and fall time have been performed. The results for shielding effectiveness of these different excitations have been presented. A simple method that uses an e...
متن کاملShielding Effectiveness of Rectangular Enclosure with Apertures and Real Receiving Antenna
In this paper, a numerical model of rectangular enclosure with apertures and a real receiving dipole antenna is considered for the purpose of accurate electric shielding effectiveness calculation. Dipole antenna is often used in practice to measure the level of electromagnetic field at some points inside the enclosure in order to estimate its shielding efficiency. Transmission-line matrix (TLM)...
