New approach to the design of corrugated horn antennas
(1997)
Contribución a congreso / Biltzarrerako ekarpena,
In this paper, we present two new corrugated horn antenna designs in circular waveguide. The first one is a
converter horn antenna from monomode circular waveguide TE11 to corrugated waveguide HE11 mode in a very efficient ...
On the determination of the phase center of gaussian horn antennas
(1998)
Contribución a congreso / Biltzarrerako ekarpena,
Gaussian horn antenna designs have experimentally demonstrated excellent performance to produce a very pure Gaussian beam mode with extremely low sidelobes and crosspolarization levels. These results make very attractive ...
Measurements of a new gaussian profile corrugated horn antenna for millimeter wave applications
(IEEE, 1998)
Contribución a congreso / Biltzarrerako ekarpena,
The measurements results of a new design of corrugated horn antennas [1, 2, 3] following the
gaussian expansion are presented in this paper. The performance of two corrugated horn
antennas of this kind was verified in ...
Generation of the HE11 mode in rectangular waveguide using gaussian techniques
(IEEE, 1999)
Contribución a congreso / Biltzarrerako ekarpena,
A new and efficient design of a rectangular corrugated waveguide mode converter,
from TE10 mode in a smooth rectangular monomode waveguide to HE11 mode in a
corrugated rectangular waveguide, is proposed. The main idea ...
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 ...
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 ...
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 ...
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 ...
