Silicon integrated subharmonic mixer on a photonic-crystal platform
(IEEE, 2021)
Artículo / Artikulua,
This paper presents a planar silicon integrated subharmonic mixer on top of a photonic-crystal platform. The local oscillator (LO) power is injected through a 2D photoniccrystal (PC) slab to a resonant cavity that effectively ...
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 ...
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 ...
Design of 300 ghz combined doubler/subharmonic mixer based on schottky diodes with integrated mmic based local oscillator
(MDPI, 2020)
info:eu-repo/semantics/article,
In this paper the design and experimental characterization of a combined doublersubharmonic mixer based on Schottky diodes which uses a 75 GHz MMIC based local oscillator is presented. This solution integrates in the same ...
Circuit and multipolar approaches to investigate the balance of powers in 2D scattering problems
(EMW Publishing, 2013)
Artículo / Artikulua,
Circuit and multipolar approaches are presented to investigate the correlation between absorption and scattering processes in 2D problems. This investigation was inspired by earlier works of Prof.R.E. Collin, which pointed ...
Surface waves of finite size electromagnetic band gap woodpile structures
(EMW Publishing, 2011)
Artículo / Artikulua,
This paper studies the surface modes at the interface of finite size Electromagnetic Band Gap (EBG) woodpile structures. The impact of different types of woodpile terminations on the properties of these surface modes is ...
Broadband radar cross-section reduction using AMC technology
(IEEE, 2013)
Artículo / Artikulua,
This paper presents the design, fabrication and characterization of a planar broadband chessboard structure to reduce the radar cross-section (RCS) of an object. The chessboard like configuration is formed by combining two ...
Decoupling of multifrequency dipole antenna arrays for microwave imaging applications
(Hindawi Publishing Corporation, 2010)
Artículo / Artikulua,
The mutual coupling between elements of a multifrequency dipole antenna array is experimentally investigated by S-parameter
measurements and planar near-field scanning of the radiated field. A multifrequency array with ...
Suberb gaussian beam efficiency corrugated horn antennas
(2010)
Contribución a congreso / Biltzarrerako ekarpena,
In this paper we are presenting the possibilities of
corrugated horn antennas that combine horizontal and
vertical corrugations.
Corrugated horn antenna noise temperature characterisation for the NRL water vapor millimeter-wave spectrometer project
(2011)
Contribución a congreso / Biltzarrerako ekarpena,
In this paper the antenna noise temperature for two different corrugated horn antennas (old model and new model) for NRL WVMS is being characterized. The whole optical system will be simulated with Ticra’s
GRASP software, ...
