IN THIS era of telecommunications when most systems are being made wireless, the need for security has increased tremendously because various signals need to be protected and isolated from each other.
Meeting both these requirements simultaneously can present a host of challenges. Currently, mobile communication and Wireless Internet Local Area Network (WLAN) systems are being designed on the basis of a detailed analysis of Radio Frequency (RF) coverage and capacity requirements. Security and privacy issues can be addressed through good design but "eavesdropping" continues to be a real vulnerability.
A revolutionary technology, called Frequency Selective Surface (FSS), is increasingly being proposed and used as an answer to the deployment of secure wireless systems for indoor environments, taking advantage of innovative techniques in building design and the use of attenuating material.
Towards the end of the eighteenth century, the American physicist D. Rittenhouse......
