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 ...
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 ...
Gaussian profiled horn antennas
(1999)
Contribución a congreso / Biltzarrerako ekarpena,
In many different applications parameters
such efficiency, gain, directivity, etc., are really
critical. By using the Gaussian techniques presented
here, the radiating features of existing horn antenna
systems can be ...
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 ...
Antena corrugada con perfil gaussiano de gran ancho de banda
(2001)
Contribución a congreso / Biltzarrerako ekarpena,
En este trabajo se presenta el diseño de una antena de bocina
corrugada con más de un 40% de ancho de banda. Los patrones
de radiación medidos coinciden muy bien con los simulados.
Esta antena se puede usar en aplicaciones ...
Diseño de filtros en guía rectangular usando estructuras PBG's
(2000)
Contribución a congreso / Biltzarrerako ekarpena,
A new application of dielectric periodic
structures (also known as PBG) to build and design
waveguide filters is presented. The periodic
structures have some stop frequency bands, band
gaps, defined by the geometry, ...
Ultra-wide band corrugated gaussian profiled horn antenna design
(IEEE, 2001)
Contribución a congreso / Biltzarrerako ekarpena,
A corrugated horn antenna design with more than 40% bandwidth is
proposed in this paper. The measured radiated field patterns have a good
agreement with the simulated ones.
This antenna can be used in applications that ...
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 ...
