Micromesh Expanded Metal for EMI Shielding White Paper

An Introduction to Expanded Metal Micromesh for EMI Shielding

Electromagnetic interference can be as simple as an annoying hiss or buzz emanating from speakers or static on a television screen. It can also be as serious as the complete disruption of mission-critical aerospace communications.

EMI shielding is the practice of reducing or blocking the Electromagnetic Field in an area using barriers made of conductive or magnetic materials. EMI shielding is typically applied to enclosures to isolate electrical devices from their surroundings and applied to cables to isolate wires from the environment through which the cable runs. The amount of reduction depends upon the type of material that is being used, its thickness, the size of the shielded volume, the frequency of the fields of interest and the size, shape, and orientation of openings in a shield.

This white paper will introduce you types of EMI, the difference between EMI and RFI, and how expanded metal micromesh can provide effective shielding. To learn more,
