[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) - Practical Isotropy and Anisotropy of 3-D Printed Artificial Foam-Like Dielectrics with Antenna Applications
摘要： The models, limitations and realization of homogenized foam-like 3-D printed dielectrics have been presented applying different fully symmetrical unit cells. The strategy for control of the absolute values of the resultant isotropic equivalent dielectric constant of these artificial dielectrics has been presented and verified and a possible anisotropy has been minimized.

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.
