New Technology: Radio-Opaque Windows for Enhanced Digital Security

The video discusses the security concerns of wireless networks and introduces a method developed by the University of Warwick to create radio opaque windows. These windows use frequency selective surfaces (FSS) to block specific wireless signals while allowing others, like mobile phone frequencies, to pass through. The technology is tunable, allowing for universal circuitry adaptable to different glass types, making it a versatile solution for changing frequency blocking needs.

What challenges does the tunable system address compared to traditional window materials?
