SCATTMAT: herramienta C.A.D. para el análisis de componentes en guía de onda circular con variaciones simétricas del radio
(1996)
Contribución a congreso / Biltzarrerako ekarpena,
In this paper, a C.A.D. tool to simulate simmetrical radial deformation microwave devices, using
the modal analysis and scattering matrix techniques is presented. The code has been developed in C++
language, working with ...
Paraxiality considerations of higher order gaussian modes
(1996)
Contribución a congreso / Biltzarrerako ekarpena,
Frequently, gaussian modes are used as free space wave equation solutions. This is not true since
they are obtained assuming certain paraxial character in them.
In this paper, we present an original study of the condition ...
Polarization selection with stacked hole array metamaterial
(AIP Publishing, 2008)
Artículo / Artikulua,
Polarization rotation or selection appears in materials with optical activity, or those with Faraday
effect, or in liquid crystals. In this letter we present a structure, with an analogous response, using
stacked ...
Negative refraction through an extraordinary transmission left-handed metamaterial slab
(American Physical Society, 2009)
Artículo / Artikulua,
In this work we present numerical and experimental results of negative refraction through a negative index
metamaterial based on miniaturized extraordinary transmission stacked subwavelength hole arrays, also known
as ...
Converging biconcave metallic lens by double-negative extraordinary transmission metamaterial
(AIP Publishing, 2009)
Artículo / Artikulua,
In this letter we present simulation and experimental results of a left-handed converging biconcave
metallic lens made of stacked subwavelength hole arrays SSHAs working in the millimeter wave
range with additional ...
Experimental demonstration of phase resonances in metallic compound gratings with subwavelength slits in the millimeter wave regime
(AIP Publishing, 2009)
Artículo / Artikulua,
We provide experimental evidence of phase resonances in metallic periodic structures in which each
period comprises several subwavelength slits of the same width. We have analyzed and measured
the response of these ...
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 ...
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 ...
Línea de transmisión cuasi-óptica con modos gaussianos de orden superior para sistemas basados en gyrotrones tecnológicos para aplicaciones cerámicas
(1997)
Contribución a congreso / Biltzarrerako ekarpena,
In this paper, a description of a new compact microwave oven system based on a tecnological
gyrotron for material processing applications is presented. The whole system has been designed by the
Institute of Applied Physics ...
New approach to the design of corrugated horn antennas
(1997)
Contribución a congreso / Biltzarrerako ekarpena,
In this paper, we present two new corrugated horn antenna designs in circular waveguide. The first one is a
converter horn antenna from monomode circular waveguide TE11 to corrugated waveguide HE11 mode in a very efficient ...
