Impact of high power interference sources in planning and deployment of wireless sensor networks and devices in the 2.4 GHz frequency band in heterogeneous environments
(MDPI, 2012)
Artículo / Artikulua,
In this work, the impact of radiofrequency radiation leakage from microwave ovens and its effect on 802.15.4 ZigBee-compliant wireless sensor networks operating in the 2.4 GHz Industrial Scientific Medical (ISM) band is ...
All-metallic ε-near-zero (ENZ) lens based on ultra-narrow hollow rectangular waveguides: experimental results
(IEEE, 2014)
Contribución a congreso / Biltzarrerako ekarpena,
Here we perform numerical and experimental investigation of plano-concave all-metallic ε-near-zero (ENZ) lens with operational frequency f = 144 GHz. The ENZ lens is achieved by stacking an array of narrow hollow rectangular ...
Experimental demonstration of metamaterials application for mitigating scan blindness in phased array antennas
(EDP Sciences, 2016)
Artículo / Artikulua,
This paper presents two metamaterial-inspired solutions to mitigate the scan blindness effects in a phased array antenna. In the first solution, portions of a bed of nails are introduced in the radome to prevent the excitation ...
Comment on “A waveguide slit array antenna fabricated with subwavelength periodic grooves Appl. Phys. Lett. 91, 143512 (2007)”
(AIP Publishing, 2008)
info:eu-repo/semantics/other,
We firmly think that it is proven that most of the ideas, results, and discussions presented in C. Huang, C. L. Du, and X. G. Luo, Appl. Phys. Lett. 91, 143512, 2007 were already present in our previous paper (M. Beruete, ...
Extraordinary transmission and left-handed propagation in miniaturized stacks of doubly periodic subwavelength hole arrays
(Optical Society of America, 2007)
info:eu-repo/semantics/article,
Metallic plates embedded between dielectric slabs and
perforated by rectangular arrays of subwavelength holes with a dense
periodicity in one of the directions support extraordinary transmission (ET)
phenomena, viz. strong ...
Broadband spoof plasmons and subwavelength electromagnetic energy confinement on ultrathin metafilms
(Optical Society of America, 2009)
info:eu-repo/semantics/article,
A complementary split ring resonator (CSRR)-based metallic
layer is proposed as a route to mimic surface plasmon polaritons. A
numerical analysis of the textured surface is carried out and compared to
previous prominent ...
Electroinductive waves role in left-handed stacked complementary split rings resonators
(Optical Society of America, 2009)
info:eu-repo/semantics/article,
In this letter it is presented a Left-Handed Metamaterial design route
based upon stacked arrays of screens made of complementary split rings
resonators under normal incidence in the microwave regime. Computation of ...
Comportamiento de propagacion electromagnetica en el apilamiento de agujeros sublambda y agujeros propagantes
(2009)
Contribución a congreso / Biltzarrerako ekarpena,
In this work, we provide more insight on the physics
underlying the transmission through subwavelength hole arrays
metaprism by comparing it with propagating hole arrays prism.
We show the critical role that the size ...
Electroinductive waves in chain of complementary metamaterial elements
(AIP Publishing, 2006)
Artículo / Artikulua,
Electronductive waves supported by chains of resonators drilled on a metallic plate are presented.
Propagation of energy comes as a consequence of the electric coupling between these resonators.
Therefore, these waves ...
Response of complementary split ring resonators in composite stratified substrate integrated waveguide
(American Institute of Physics, 2017)
Artículo / Artikulua,
In this work, the behavior of a Complementary Split Ring Resonator (CSRR) operating within the
quasi-static resonance regime and embedded in a composite stratified Substrate Integrated
Waveguide (SIW) with two different ...
