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 ...
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 ...
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 ...
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 ...
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 ...
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, ...
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 ...
Fe-rich ferromagnetic wires for self-sensing materials
(IEEE, 2012)
Artículo / Artikulua,
The possibility of using Fe-rich wires in mechanical stress self-sensing materials is investigated. To this end, a retrieval technique aimed to characterize the high-frequency magnetoimpedance effect in ferromagnetic wires ...
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 ...
