Ultra-long-range Bessel beams via leaky waves with mitigated open stopband Open
Open stopband (OSB) mitigation techniques are commonly used to improve the far-field radiating properties of leaky-wave antennas based on periodic structures. Recently, leaky waves have been proposed to focus energy in the near field throu…

Complete Open-Stopband Suppression Using Sinusoidally Modulated Anisotropic Metasurfaces Open
A novel and general approach is presented for the complete suppression of the open-stopband effects in circularly polarized one-dimensional periodic leaky-wave antennas using anisotropic modulated metasurfaces. A theoretical justification …

Dual-mode hyperbolicity, supercanalization, and leakage in self-complementary metasurfaces Open
Anisotropic Self-Complementary Metasurfaces (SC-MTSs) are structures constituted by an alternation of complementary inductive and capacitive strips, which are “self-dual” according to Babinet’s duality principle. They support the propagati…
