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 ... -
Barrido del haz en antena de onda de fuga basada en metasuperficie mediante cristales líquidos
Abdo-Sánchez, María Elena; Epstein, Ariel; Eleftheriades, George V. (Iñigo Cuiñas Gómez, 2021-09-23)
In this communication, the reconfigurability mechanisms for beam steering at a fixed frequency in a leakywave antenna based on Huygens metasurfaces are reviewed. A preliminary design for a forward-to-backward scanning ... -
Experimental Verification of a Leaky-Wave Antenna Based on Bianisotropic Huygens’ Metasurface
Abdo-Sánchez, María Elena; Chen, Michael; Epstein, Ariel; Eleftheriades, George V. (2019-05-06)
Abstract—In this communication, the experimental verification of a leaky-wave antenna that uses a Huygens’ metasurface to have a control on the radiation parameters is addressed. The antenna consists of a parallel-plate ... -
Implementación de antena leaky-wave basada en metasuperficie de Huygens
Abdo-Sánchez, María Elena; Epstein, Ariel; Eleftheriades, George V. (2018-09-07)
In this communication, the implementation of a leaky-wave antenna based on bianisotropic Huygens’ metasurface is addressed. It consists of a parallel-plate waveguide in which the top plate is replaced by a metasurface. It ... -
Leaky-Wave antennas with arbitrary radiation based on bianisotropic Huygens’ metasurfaces
Abdo-Sánchez, María Elena; Epstein, Ariel; Eleftheriades, George V. (2018-06-05)
In this contribution, we present the application of Huygens’ metasurfaces (HMS) to the arbitrary design of leaky-wave antennas (LWAs). These metasurfaces have demonstrated their capabiity to tailor the electromagnetic waves ... -
On the use of bianisotropic huygens' metasurfaces to build leaky-wave antennas
Abdo-Sánchez, María Elena; Chen, Michael; Epstein, Ariel; Eleftheriades, George V. (2019-07-16)
Huygens' metasurfaces are considered a powerful tool to achieve anomalous electromagnetic field transformations. They consist of an artifcial surface built of pairs of collocated electric and magetic dipoles that force ... -
Physical Implementation of Leaky-Wave Antenna with Engineered Aperture Distribution Based on Bianisotropic Huygens Metasurfaces
A methodology based on omega-type bianisotropic Huygens’ metasurfaces is presented to control the aperture field distribution of leaky-wave antennas. The studied structure is a parallel-plate waveguide with the top plate ... -
Reconfigurability mechanisms with scanning rate control for omega-bianisotropic Huygens’ metasurface leaky-wave antennas
Abdo-Sánchez, María Elena; Epstein, Ariel; Eleftheriades, George V. (IEEE, 2019)
In this paper, different reconfigurability mechanisms are proposed to scan the pointing direction at a fixed frequency of recently-proposed leaky-wave antennas based on omega-bianisotropic Huygens' metasurfaces. The ...
