2021. Digitally Tunable Frequency Selective Surface for a Physical Layer Security System in the 5 GHz Wi-Fi Band. 2020 International Symposium on Antennas and Propagation (ISAP). :267–268.
In this work, a digitally tunable Frequency Selec-tive Surface (FSS) for use in Physical Layer Security (PLS) systems is presented. The design of a unit cell is described, which is optimized by simulations for the frequency range of 5 GHz indoor Wi-Fi. Based on the developed unit cell, a prototype with 64 binary switchable elements is set up. The performance of the surface is demonstrated by measurements.
