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 ...
Ultra-wide band corrugated profiled horn antenna design
(IEEE, 2002)
Artículo / Artikulua,
Nowadays, an increasing number of applications need stable radiation patterns
with low sidelobes and low crosspolar levels in a very wide bandwidth. Gaussian Profiled
Horn Antennas (GPHA’s) have demonstrated its feasibility ...
Review on electromagnetic band gap technology and applications
(URSI, 2004)
Artículo / Artikulua,
This paper reviews the primary application areas of Electromagnetic BandGap (EBG) technology at
microwave and (sub)millimetre wave frequencies. Examples of EBG configurations in the microwave
region are shown and include ...
A metamaterial T-junction power divider
(IEEE, 2007)
Artículo / Artikulua,
A metamaterial based compact microstrip T-junction
power divider working at 10 GHz is proposed. The metamaterial
unit cell consists of microstrip gaps and via holes whose behavior
is equivalent to the combination of ...
Terahertz time domain spectroscopy allows contactless monitoring of grapevine water status
(Frontiers Media, 2015)
info:eu-repo/semantics/article,
Agriculture is the sector with the greatest water consumption, since food production is frequently based on crop irrigation. Proper irrigation management requires reliable information on plant water status, but all the ...
Magnetic dipole super-resonances and their impact on mechanical forces at optical frequencies
(Optical Society of America, 2014)
info:eu-repo/semantics/article,
Artificial magnetism enables various transformative optical
phenomena, including negative refraction, Fano resonances, and unconventional
nanoantennas, beamshapers, polarization transformers and perfect
absorbers, and ...
Optimization of a pin surface as a solution to suppress cavity modes in a packaged W-band microstrip receiver
(IEEE, 2014)
Artículo / Artikulua,
A pin surface structure has been used in the upper
metal plate of a packaged W-band RF front-end receiver in order
to suppress the propagation of unwanted modes. A full parametric
analysis of the periodic structure within ...
A multipolar analysis of near-field absorption and scattering processes
(IEEE, 2013)
Artículo / Artikulua,
A multipolar formulation is adopted to investigate
the absorption and scattering processes involved in near-field
interactions. This approach allows one to determine the upper
bounds for the absorbed and radiated powers ...
Least upper bounds of the powers extracted and scattered by bi-anisotropic particles
(IEEE, 2014)
Artículo / Artikulua,
The least upper bounds of the powers extracted and
scattered by bi-anisotropic particles are investigated analytically.
A rigorous derivation for particles having invertible polarizability
tensors is presented, and the ...
