Electromagnetic cloaking with canonical spiral inclusions
(IOP Publishing Ltd., 2008)
Artículo / Artikulua,
We report an electromagnetic cloaking structure that is composed of identical canonical spiral particles. By using the Clausius-Mosotti formula, the electric and magnetic polarizabilities of a single spiral particle are ...
Arrangements of via-holes in microstrip lines as metallodielectric periodic structures
(Wiley, 2000)
Artículo / Artikulua,
In this paper, the use of via holes in microstrip lines to design periodic structures that can be regarded as metallodielectric electromagnetic crystals is analyzed. The proposed novel periodic structures achieve a notably ...
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 ...
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 ...
Alimentadores gaussianos en guía de onda rectangular
(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 ...
