Shielding effectiveness

Shielding effectiveness refers to how well a barrier or material can block or reduce electromagnetic radiation, such as radio waves, microwaves, or electric fields. It measures the ability of the shield to prevent electromagnetic energy from passing through, protecting sensitive equipment or signals from interference, or containing emissions. The effectiveness is often expressed in decibels (dB); higher values indicate better shielding performance. Factors influencing shielding effectiveness include the material's electrical conductivity, thickness, and frequency of radiation. Essentially, it helps ensure that unwanted electromagnetic signals do not disrupt functioning or compromise security.
