Terahertz wave transmission in flexible polystyrene-lined hollow metallic waveguides for the 2.5-5 THz band
(Optical Society of America, 2013)
info:eu-repo/semantics/article,
A low-loss and low-dispersive optical-fiber-like hybrid HE11 mode is developed within a wide band in metallic hollow waveguides if their inner walls are coated with a thin dielectric layer. We investigate terahertz (THz) ...
Tunable electro-optic wavelength filter based on lossy-guided mode resonances
(Optical Society of America, 2013)
info:eu-repo/semantics/article,
In this work an optical fiber tunable filter based on lossy guided-mode resonances (LGMR) is proposed. It consists of a multilayer structure deposited onto the surface of a plastic cladding removed multimode fiber. The ...
Terahertz epsilon-near-zero graded-index lens
(Optical Society of America, 2013)
info:eu-repo/semantics/article,
An epsilon-near-zero graded-index converging lens with planar
faces is proposed and analyzed. Each perfectly-electric conducting (PEC)
waveguide comprising the lens operates slightly above its cut-off frequency
and has ...
Highly-efficient fully resonant vertical couplers for InP active-passive monolithic integration using vertically phase matched waveguides
(Optical Society of America, 2013)
info:eu-repo/semantics/article,
A new active-passive monolithic integration approach for
photonic components based on vertical evanescent coupling is presented.
Two vertically stacked waveguides are used in order to provide full
resonant power transfer ...
Multiplexing of six micro-displacement suspended-core Sagnac interferometer sensors with a Raman-Erbium fiber laser
(Optical Society of America, 2013)
info:eu-repo/semantics/article,
This work experimentally demonstrates a long-range optical
fiber sensing network for the multiplexing of fiber sensors based on
photonic crystal fibers. Specifically, six photonic crystal fiber sensors
which are based ...
Single-longitudinal mode laser structure based on a very narrow filtering technique
(Optical Society of America, 2013)
info:eu-repo/semantics/article,
A narrow filtering technique based on the spectral overlapping of
two uniform FBGs and applied to obtain a Single Longitudinal Mode
(SLM) laser is proposed and demonstrated in this work. The two FBGs are
spectrally ...
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, ...
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 ...
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 ...
