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 ...
Línea de transmisión cuasi-óptica con modos gaussianos de orden superior para sistemas basados en gyrotrones tecnológicos para aplicaciones cerámicas
(1997)
Contribución a congreso / Biltzarrerako ekarpena,
In this paper, a description of a new compact microwave oven system based on a tecnological
gyrotron for material processing applications is presented. The whole system has been designed by the
Institute of Applied Physics ...
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” ...
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 ...
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 ...
