Electromagnetic cloaking with canonical spiral inclusions
(IOP Publishing Ltd., 2008)
Artículo / Artikulua,
We report an electromagnetic cloaking structure that is composed of identical canonical spiral particles. By using the Clausius-Mosotti formula, the electric and magnetic polarizabilities of a single spiral particle are ...
Design of 300 ghz combined doubler/subharmonic mixer based on schottky diodes with integrated mmic based local oscillator
(MDPI, 2020)
info:eu-repo/semantics/article,
In this paper the design and experimental characterization of a combined doublersubharmonic mixer based on Schottky diodes which uses a 75 GHz MMIC based local oscillator is presented. This solution integrates in the same ...
Silicon integrated subharmonic mixer on a photonic-crystal platform
(IEEE, 2021)
Artículo / Artikulua,
This paper presents a planar silicon integrated subharmonic mixer on top of a photonic-crystal platform. The local oscillator (LO) power is injected through a 2D photoniccrystal (PC) slab to a resonant cavity that effectively ...
Arrangements of via-holes in microstrip lines as metallodielectric periodic structures
(Wiley, 2000)
Artículo / Artikulua,
In this paper, the use of via holes in microstrip lines to design periodic structures that can be regarded as metallodielectric electromagnetic crystals is analyzed. The proposed novel periodic structures achieve a notably ...
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 ...
Very short and efficient feeder design from monomode waveguide
(IEEE, 1997)
Contribución a congreso / Biltzarrerako ekarpena,
In this paper, we present an original and short corrugated horn antenna
profile to obtain the HE11 corrugated circular waveguide mode exciting with
a pure TE11 monomode smooth circular waveguide mode. We will obtain ...
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
(1996)
Contribución a congreso / Biltzarrerako ekarpena,
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 ...
