High order mode beam waveguide for technological medium power millimeter wave applications
(1995)
Contribución a congreso / Biltzarrerako ekarpena,
The use of medium power millimeter wave CW gyrotrons (10-
30 kW and 30-100 GHz) has several potential applications in
advanced materials processing. Since a stochastic field
distribution in the applicator is desirable ...
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 ...
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 ...
Analysis of surface-plasmon-like modes under an engineering perspective
(2011)
Contribución a congreso / Biltzarrerako ekarpena,
In this communication we show how one can exploit equivalent circuits to analyze surface-plasmon-like modes (slit and hole arrays, Sievenpiper mushrooms and coaxial hole arrays) and to propose new designs with outstanding ...
New regimes to achieve enhanced transmission through subwavelength hole arrays
(2011)
Contribución a congreso / Biltzarrerako ekarpena,
In this communication we present millimetre- and THz-waves experimental confirmation of enhanced
transmission through subwavelength hole arrays with rectangular lattice when the incident electric field is parallel to ...
The beauty of anisotropy in extraordinary transmission fishnet metamaterials
(2011)
Contribución a congreso / Biltzarrerako ekarpena,
In this work, we explore both numerically and experimentally, the possibility to obtain positive and negative refraction regimes that depend on the wave polarization, exploiting the strong anisotropy of extraordinary ...
