Measurements of Shielding Effectiveness for Textile-Based Enclosure
Subject area: Science,Engineering and Technology · Area of research: EMI &EMC

Abstract
Electromagnetic interference (EMI) is one of the most critical challenges in modern electronics, especially with the rapid expansion of wireless communication and compact circuit systems. Conventional metallic shielding methods, while effective, are heavy, rigid, and unsuitable for modern wearable or flexible electronics. To overcome these issues, this paper presents a MATLAB-based analysis of EMI shielding effectiveness (SE) for a textile-based enclosure using a polyester fabric coated with copper (Cu) and nickel (Ni). The simulation evaluates absorption, reflection, and multiple reflection losses across frequencies from 1 MHz to 1 GHz. A 3D model of the textile enclosure was also developed to visualize the electromagnetic field interaction. Results show that SE increases with frequency, with an average value of 45 dB and a peak of more than 100 dB. The findings confirm that Cu/Ni-coated textiles can serve as efficient, lightweight alternatives for EMI shielding in flexible electronic systems.
