Electromagnetic interference (EMI) presents a significant challenge in today's industrial and commercial sectors. The demand for reliable shielding solutions is growing as electronics become more sophisticated and are deployed in sensitive environments. Traditional reliance on metal-based materials for EMI shielding remains effective but often comes with weight, cost, and corrosion limitations. However, various materials are now available that offer practical, proven solutions for real-world applications in industries such as telecommunications, automotive, aerospace, and medical devices. Fundamental Principles of EMI Shielding EMI shielding works by using materials that reflect or absorb electromagnetic waves, preventing interference from disrupting the functioning of electronic devices. Metals like aluminum, copper, and nickel have long been used due to their high conductivity. Still, their practical limitations (e.g., weight and susceptibility to ...
