Here's another EMI example:

Electromagnetic interference shielding properties of polymer derived SiC-Si3N4 composite ceramics

As a result, the electromagnetic interference (EMI) shielding performance of the as-prepared ceramic annealed at 1400?°C reaches up to 36?dB, meaning more than 99.9% of EM energy is shielded. The low porosity and high EMI shielding performance enable SiC-Si3N4 composite ceramics to be a promising electromagnetic shielding and structural material.
