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 ...
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 ...
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 ...
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 ...
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 ...
