Loss analysis of air-core photonic crystal fibers [PDF]
, 2003 By using a multipole moment approach, we analyze the loss of an air-core photonic crystal fiber and demonstrate that it is possible reduce the transmission loss that is due to photon radiation leakage through the photonic crystal cladding to a level ...

Birefringence analysis of multilayer leaky cladding optical fibre [PDF]
, 2010 We analyse a multilayer leaky cladding (MLC) fibre using the finite element method and study the effect of the MLC on the bending loss and birefringence of two types of structures: (i) a circular core large-mode-area structure and (ii) an elliptical ...

IEEE Access, 2023 Amorphous alloy has been proposed to replace silicon steel as the stator core material of high-speed asynchronous motors so as to reduce their core losses. However, it is found that this is at the expense of increasing the copper loss.

, 2014 We present a novel mechanism to enhance the mass-loss rates of massive stars shortly before their explosion. The neutrino luminosities of the stellar core of massive stars become larger as they get closer to the time of the core collapse.

Reflection electron energy loss spectroscopy during initial stages of Ge growth on Si by molecular beam epitaxy [PDF]
, 1991 Using a conventional reflection high-energy electron diffraction gun together with an electron energy loss spectrometer, we have combined in situ measurements of inelastic scattering intensities from Si L2,3 and Ge L2,3 core losses with reflection ...

Temperature dependence of core loss in cobalt substituted Ni-Zn-Cu ferrites
, 2010 The temperature dependence of core loss in cobalt substituted Ni-Zn-Cu ferrites was investigated. Co2+ ions are known to lead to a compensation of the magneto-crystalline anisotropy in Ni-Zn ferrites, at a temperature depending on the cobalt content and ...

Ultra-large bandwidth hollow-core guiding in all-silica Bragg fibers with nano-supports [PDF]
, 2004 We demonstrate a new class of hollow-core Bragg fibers that are composed of concentric cylindrical silica rings separated by nanoscale support bridges. We theoretically predict and experimentally observe hollow-core confinement over an octave frequency ...

Low-Cost High-Sensitivity Strain and Temperature Sensing Using Graded-Index Multimode Fibers [PDF]
, 2007 We report a low-loss, low-cost high-sensitivity all-fiber strain and temperature sensor based on mode interference in graded-index multimode fibers. Blueshifts with strain and temperature sensitivities of 18.6 pm/microstrain and 58.5 pm/°C have been ...
