In today’s modern world, electronic devices are becoming increasingly widespread and complex, creating a critical need to shield both other devices and humans from electromagnetic waves. Electromagnetic radiation can negatively impact the performance of electronic equipment and even pose potential risks to human health. From household appliances and mobile phones to industrial systems and military applications, electromagnetic interference (EMI) can lead to severe consequences such as operational disruptions, reduced efficiency, and even complete device failure.

However, reducing the use of electronic devices is not always feasible. Instead, the focus should be on minimizing the penetration of electromagnetic waves generated by these devices. This article will delve into the mechanisms of EMI shielding and explore optimal solutions to ensure both safety and performance for modern electronic systems.
