Circuital and Numerical Models for Calculation of Shielding Effectiveness of Enclosure with Apertures and Monitoring Dipole Antenna Inside
In this paper, circuital and numerical models of metal enclosure with apertures are considered for the purpose of accurate shielding effectiveness calculation. An improved circuital model is presented to account for the presence of receiving dipole antenna which is often used in practice to measure the level of electromagnetic field at selected points inside the enclosure. Receiving antenna of ...
متن کاملFast Calculation of the Shielding Effectiveness for a Rectangular Enclosure of Finite Wall Thickness and with Numerous Small Apertures
In this paper, an extremely fast technique is introduced to evaluate the shielding effectiveness of a rectangular enclosure of finite wall thickness and numerous square or circular small apertures subject to a normally incident plane wave. The technique is based on the traditional waveguide circuit model where the enclosure is replaced with an equivalent shorted transmission line. In the propos...
متن کاملNumerical Simulation of Coupling Coefficient of Apertures in Missile Enclosure
Aperture coupling is the main coupling mode through which electromagnetic pulse (EMP), ultra wideband (UWB) and high power microwave (HPM) can disturb or damage electronic equipments of the missile enclosure. To get knowledge of the coupling effects of apertures with different shapes and positions, coupling processes of HPM into the missile enclosure are investigated. The simulation results ind...
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 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)...
