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 ...
Antenas de bocina optimizadas para acoplar modos gaussianos de orden superior
(1995)
Contribución a congreso / Biltzarrerako ekarpena,
The concept of higher order free space modes, gaussian-like beam modes can be applied to
efficiently transport the power generated by a gyrotron for technological applications. Waveguide modes
can be coupled properly to ...
Estudio de la posibilidad de utilizar modos de orden superior en guías de onda cuasi-ópticas
(1995)
Contribución a congreso / Biltzarrerako ekarpena,
The possibility to employ low power gyrotron tubes (10-30 kW, CW) at millimeter wave frequencies
(30-100 GHz) has potential applications in advanced ceramic sintering, surface coating, radar, remote
sensing, etc.. In ...
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 ...
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 ...
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 ...
Nuevas consideraciones al diseño de conversores de modos TE0m-TE0n para aplicaciones de alta potencia a frecuencias milimétricas
(1996)
Contribución a congreso / Biltzarrerako ekarpena,
In this work, the new results of a study about the general Kovalev’s coherence principle are
presented. As we will show here, despite Kovalev presents the coherence principle as general, only the
fundamental case can be ...
Consideraciones de paraxialidad en modos gaussianos de orden superior
(1996)
Contribución a congreso / Biltzarrerako ekarpena,
Usually, the gaussian beam modes are assumed to be solutions of the wave equation in the free
space. Nevertheless, these modes are obtained supposing some paraxial restrictions. Therefore, we will
have to check if our ...
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 ...
