Application of Huygens’ Metasurfaces to the Arbitrary Design of a Leaky-Wave Antenna
Abdo-Sánchez, María Elena
; Epstein, Ariel; Eleftheriades, George V. (2017-09-13)
Leaky-wave antennas are guiding structures that leak power along their length. Their radiation is mainly characterized by the propagation constant (leakage factor and phase constant) of the traveling wave. In this ... -
Arbitrary and Rigorous Aperture Illumination Synthesis in Huygens’ Metasurface-Based Leaky-Wave Antennas.
Mateos-Ruiz, Pablo; Killamsetty, Vinay Kumar; Epstein, Ariel; Abdo-Sánchez, María Elena (IEEE, 2025-03-17)
Omega-type bianisotropic Huygens’ metasurfaces offer a novel approach for controlling the aperture field distribution of leaky-wave antennas. This paper presents a methodology utilizing a parallel-plate waveguide with a ... -
