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 ...
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 ...
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 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 ...
Near-field electromagnetic trapping through curl-spin forces
(American Physical Society, 2013)
Artículo / Artikulua,
Near-field electromagnetic trapping of particles is generally obtained bymeans of gradient forces. In this paper,
we discuss the attractive behavior of curl-spin forces, as well as their potential for near-field ...
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 ...
Electromangetic force density in electrically and magnetically polarizable media
(American Physical Society, 2013)
Artículo / Artikulua,
The force density induced by electromagnetic fields in electrically and magnetically polarizable media is
studied analytically. Different formulations of the force density as a function of field-related quantities, ...
Dual circularly polarized broadside beam metasurface antenna
(IEEE, 2016)
Artículo / Artikulua,
This paper presents the design of a modulated metasurface (MTS) antenna capable to provide both righthand (RH) and left-hand (LH) circularly polarized (CP) boresight
radiation at Ku-band (13.5 GHz). This antenna is based ...
