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 ...
Generación del modo HE11 a partir de una guía circular lisa monomodo
(1996)
Contribución a congreso / Biltzarrerako ekarpena,
In this paper, we present an original taper design to obtain the HE11 corrugated circular waveguide
mode exciting with a pure TE11 monomode smooth circular waveguide mode.
The proposed corrugated taper has a longitudinal ...
Diseño óptimo de antenas de bocina multimodo para excitar un haz gaussiano fundamental de alta pureza
(1996)
Contribución a congreso / Biltzarrerako ekarpena,
In this paper, we present an original and optimal multimode horn antenna design to excite the
fundamental Gaussian beam from an overmoded waveguide. In particular, we focus the study in overmoded
circular corrugated ...
SCATTMAT: a mode matching and generalized scattering matrix code for personal computers in a windows environment
(1997)
Contribución a congreso / Biltzarrerako ekarpena,
In this paper, a computer aided design tool is presented to simulate symmetrical radially
deformed circular waveguide microwave components. This tool works with the well-known “Mode
Matching and Scattering Matrix” ...
Optimized antenna system for low power testing of the quasioptical transmission line at TJ-II experiment

In this paper we present a high performance antenna system to carry out low power testing of
the main parameters of the quasioptical transmission line system for Electron Cyclotron Resonance
Heating (ECRH) at TJ-II ...
Gaussian beam propagation versus Huygens method in non-paraxial conditions
(1997)
Contribución a congreso / Biltzarrerako ekarpena,
In this paper, we present a study about the difference between Gaussian beam propagation and Huygens method to obtain the radiation pattern in the case of non-paraxial conditions. We fix a way to determine the error in the ...
