[IEEE 2018 12th International Congress on Artificial Materials for Novel Wave Phenomena (Metamaterials) - Espoo, Finland (2018.8.27-2018.9.1)] 2018 12th International Congress on Artificial Materials for Novel Wave Phenomena (Metamaterials) - Recent Developments in the Design of Waveform-Selective Mantle Cloaks for Antenna Applications

摘要： In this contribution, we investigate the idea of a waveform selective cloak for antenna applications. To achieve this purpose, a conventional mantle cloak designed to hide a wire antenna is loaded with a lumped-element circuit. Exploiting the peculiar time-domain response of the circuit, the cloak is able to modify its behavior either as an invisibility device or a perfect electric conductor when the impinging signal switches from a pulse (PW) to a continuous (CW) wave, respectively. The proposed configuration paves the way to a new generation of tunable and reconfigurable cloaking devices for antenna applications.
