Lentes metálicas basadas en el fenómeno de transmisión extraordinaria para conseguir índices de refracción negativos
(2009)
Contribución a congreso / Biltzarrerako ekarpena,
In this communication we report plano-concave
and bi-concave metamaterial lenses based on the close stack of
subwavelegnth hole arrays. Contrary to what is expected from
cut-off holes, an engineered array of holes ...
Mejora de antenas metalo-dieléctricas en la banda de frecuencias GSM-UMTS mediante elementos en transmisión extraordinaria
(2009)
Contribución a congreso / Biltzarrerako ekarpena,
In this work a dual band GSM/UMTS antenna is
proposed. The antenna is based on a stacked planar structure,
where the combination of collimation by Enhanced
Transmission and the use of parasitic director elements is ...
