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 ...

High Performance Planar Magnetics Based on an Unbalanced-Flux Approach
IEEE Open Journal of Power Electronics, 2023 This paper presents a new design concept to increase the efficiency and the power density of planar magnetics. In contrast to the existing magnetics, which are built using the balanced magnetic flux density design, the proposed design concept generates ...

In situ real-time analysis of alloy film composition and segregation dynamics with parallel detection reflection electron energy loss spectroscopy [PDF]
, 1997 Real-time measurements of GexSi1 – x/Si(001) composition and segregation dynamics in Sn/Si(001) in molecular beam epitaxy are demonstrated using parallel detection reflection electron energy loss spectroscopy.

Curvature-related eddy-current losses in laminated axial flux machine cores [PDF]
, 2005 In this paper we present an axiperiodic quasi-static model to evaluate the magnetic flux density distribution and power loss due to curvature related radial flux in the laminated core of axial flux machines.

The Impact of Progenitor Mass Loss on the Dynamical and Spectral Evolution of Supernova Remnants [PDF]
, 2017 There is now substantial evidence that the progenitors of some core-collapse supernovae undergo enhanced or extreme mass loss prior to explosion.

Asymptotic analysis of silicon based Bragg fibers [PDF]
, 2003 We developed an asymptotic formalism that fully characterizes the propagation and loss properties of a Bragg fiber with finite cladding layers. The formalism is subsequently applied to miniature air-core Bragg fibers with Silicon-based cladding mirrors ...

Co-axial dual-core resonant leaky fibre for optical amplifiers [PDF]
, 2008 We present a co-axial dual-core resonant leaky optical fibre design, in which the outer core is made highly leaky. A suitable choice of parameters can enable us to resonantly couple power from the inner core to the outer core. In a large-core fibre, such

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.
