Epsilon-near-zero metalenses operating in the visible
(Elsevier, 2016)
Artículo / Artikulua,
Several converging lenses working in the permittivity near to zero (ENZ) regime at optical frequencies are designed using an array of metal-dielectric-metal plasmonic waveguides. These plasmonic waveguides show a dispersive ...
Metamaterials and plasmonics applied to devices based on periodic structures at high frequencies: microwaves, terahertz and optical range
(2016)
Tesis doctoral / Doktoretza tesia,
Esta tesis muestra el trabajo de investigación desarollado bajo el programa de doctorado “tecnología de las comunicaciones” de la Universidad Pública de Navarra (UPNA), para el grado de Doctor (PhD) en Ingenieria de ...
Experimental realization of an epsilon-near-zero graded-index metalens at terahertz frequencies
(American Physical Society, 2017)
Artículo / Artikulua,
The terahertz band has been historically hindered by the lack of efficient generators and detectors, but a series of recent breakthroughs have helped to effectively close the “terahertz gap.” A rapid development of terahertz ...
Experimental demonstration of a millimeter-wave metallic ENZ lens based on the energy squeezing principle
(IEEE, 2015)
info:eu-repo/semantics/article,
The performance of an epsilon-near zero (ENZ) plano-concave lens is experimentally demonstrated and verified at the D-band of the millimeter-waves. The lens is comprised of an array of narrow metallic waveguides near cut-off ...
