Shielding Effectiveness of a Metallic Perforated Enclosure by Mesh-Free Method

ABSTRACT:

In this paper, an efficient mesh-free method (MFM) is introduced to guage the shielding effectiveness of a metallic enclosure with aperture. To this end, equivalent magnetic current densities and their relative electrical vector potentials are assumed on both sides of the aperture. Magnetic current of each aspect is related to its vector potential, using an integrating operator together with proper Inexperienced's functions. Then, the electromagnetic field at every aspect is obtained by a differential operation on its respective electrical vector potential. Enforcing the continuity of the tangential magnetic and electrical fields on the aperture ends up in 2 decoupled differential and integral equations that are solved along by using proper shaping functions for the assumed magnetic currents and electrical vector potentials at the defined nodes. The proposed technique is validated by the industrial software FEKO and measurements. Furthermore, it is shown that the proposed MFM is terribly efficient compared to two similarly formulated efficient technique-of-moments-primarily based strategies.
