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 ...
Optimum horn antennas for high order mode beam waveguides
(1995)
Contribución a congreso / Biltzarrerako ekarpena,
Higher order free space modes can be considered as serious candidates for power millimeter wave transmission in advanced material processing by using medium power CW gyrotrons. These modes can be propagated in a beam ...
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 ...
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
(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 ...
