The Basics of Shielding: A Comprehensive Guide

In today's digital world, shielding from electromagnetic fields (EMF) has become essential. From IT forensics to medical technology, shielding plays a critical role in ensuring the proper function of our devices and the security of our data. In this blog post we will explain the basics of shielding and how companies like Shieldex are helping to address the challenges of EMF shielding.

What is shielding?

Shielding is the process by which a material is used to block or reduce the propagation of electromagnetic fields or radiation. There are different types of shielding, including electromagnetic shielding, which is used to protect electronic devices from electromagnetic interference (EMI).

Why is shielding important?

Electromagnetic fields can affect the performance of electronic devices and even lead to data loss. Shielding can minimize these interferences and improve device performance and reliability. In addition, shielding is also important to ensure the security and privacy of data by preventing electromagnetic signals from being intercepted.

Types of shielding

There are different types of shielding that can be used depending on the application and requirements. This includes:

Electromagnetic shielding

Electromagnetic shielding is the most common type of shielding and is used to protect electronic devices from EMI. It can be made of various materials, including metal foils, metallized textiles, metal meshes or special shielding varnishes.

Radio frequency shielding

Radio frequency shielding is used to protect devices from interference from radio frequency signals. It is particularly important in areas such as telecommunications and broadcasting, where avoiding interference is crucial.

Shielding of cables

Cable shielding is a special type of shielding used to protect data and power cables from EMI. It can help improve signal quality and prevent data loss.
