Dielectric Resonator Antennas and MIMO DRA

, 2020
Dielectric resonator antenna (DRA) is the new area of research because of its inherent advantages over traditional microstrip patch antennas. Some of the advantages of DRA are low ohmic losses due to dielectric material body, more degree of freedom due to a three-dimensional structure, high radiation efficiency, large bandwidth and easily excited by a ...

Strong Mode Coupling and Maximum Directional Absorption in Reciprocal Bianisotropic Metasurfaces

Nanophotonics, Volume 15, Issue 12, 25 June 2026.
Symmetry breaking in q‐BIC dielectric metasurfaces enables strong electromagnetic coupling between electric and magnetic modes, leading to their hybridization and Rabi‐like splitting. This mechanism produces pronounced reciprocal bianisotropy and dual‐band asymmetric absorption under opposite illumination directions, offering a compact framework for ...
