Experimental validation of a Ku-band dual circularly polarized metasurface antenna
(IEEE, 2018)
Artículo / Artikulua,
The experimental validation of a Ku-band dual circularly polarized (CP) broadside-beam metasurface (MTS) antenna is presented. A radially modulated anisotropic single layer MTS has been synthesised employing sub-wavelength ...
A comprehensive analysis of the absorption spectrum of conducting ferromagnetic wires
(IEEE, 2012)
Artículo / Artikulua,
A detailed analysis of the absorption spectrum of conductive ferromagnetic wires is presented. The absorption spectrum is computed from the solution to the scattering problem, and circuit models are formulated to clarify ...
Grating lobes in higher-order correlation functions of arrays of quantum emitters: directional photon bunching versus correlated directions
(MDPI, 2019)
Artículo / Artikulua,
Recent advances in nanofabrication and optical manipulation techniques are making it possible to build arrays of quantum emitters with accurate control over the locations of their individual elements. In analogy with ...
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 ...
Evanescently fed electromagnetic band-gap horn antennas and arrays
(IEEE, 2012)
Artículo / Artikulua,
The design of a horn antenna based on electromagnetic band-gap structures (EBGs) and fed by evanescent fields in the containing periodic structure is presented. Such all-dielectric antennas can form compact arrays and ...
Induction theorem analysis of resonant nanoparticles: design of a huygens source nanoparticle laser

We propose an advanced formulation of standard antenna theory for the basic investigation and design of resonant nanoparticles. This methodology is based on transforming the original scattering problem into a radiation ...
Superbackscattering antenna arrays
(IEEE, 2015)
Artículo / Artikulua,
This article discusses the theory, design and practical implementation of superbackscattering antenna arrays. In analogy with Uzkov’s maximal directivity theorem, it is demonstrated that the maximal backscattering ...
Upper bounds on scattering processes and metamaterial-inspired structures that reach them
(IEEE, 2014)
Artículo / Artikulua,
The physical limitations on time-harmonic scattering processes are investigated on the basis of the optical theorem. Previously derived least upper bounds on the total scattering and absorption cross-sections are obtained ...
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 ...
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, ...
