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 ...
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 ...
