Tech News 1: Electromagnetic wave shielding flexible films with near-zero reflection in the 5G frequency band

Post by bob_turner »

A research team led by Dr. Sang-Bok Lee and Byeongjin Park in the Department of Functional Composites at the Korea Institute of Materials Science (KIMS) succeeded in developing the world's first ultra-thin composite film. This film does not reflect electromagnetic waves for 5G communication but absorbs more than 90% of it. The technology can solve the secondary interference problem of electromagnetic waves for 5G communication frequency over 26 GHz.
