Fast ion JET diagnostics: confinement and losses [PDF]

AIP Conference Proceedings, 2008
A study of magnetically confined fast ions in tokamaks plays an important role in burning plasma research. To reach ignition and steady burning of a reactor plasma an adequate confinement of energetic ions produced by NBI heating, accelerated with ICRF and born in fusion reactions is essential to provide efficient heating of the bulk plasma.

Sensitivity of confinement losses in optical fibers to modeling approach

Optics Express, 2023
A prime objective of modeling optical fibers is capturing mode confinement losses correctly. This paper demonstrates that specific modeling choices, especially regarding the outer fiber cladding regions and the placement of the computational boundary, have significant impacts on the calculated mode losses.

Supermode Characteristics of Nested Multiple Hollow-Core Anti-Resonant Fibers

Photonics, 2022
Mode-division multiplexing (MDM) can achieve ultra-high data capacity in optical fiber communication. Several impressive works on multicore fiber (MCF), multi-mode fiber, and few-mode multicore fiber have made significant achievements in MDM.

Confinement losses in microstructured optical fibers [PDF]

Optics Letters, 2001
We describe a multipole formulation that can be used for high-accuracy calculations of the full complex propagation constant of a microstructured optical fiber with a finite number of holes. We show how the imaginary part of the microstructure, which describes confinement losses not associated with absorption, varies with hole size, the number of rings

Confinement loss of anti-resonant capillaries with curved boundaries

Optics Express, 2021
A systematic analysis of the dependence of the confinement loss of an anti-resonant capillary on the curvature of the core surround is presented. The core boundary is described by circular arcs and the construction allows for a wide range of core shapes to be considered.

Sodium-Based Cylindrical Plasmonic Waveguides in the Near-Infrared

Nanomaterials, 2022
Subwavelength optical field confinement and low-loss propagation are of great significance for compact photonic integration. However, the field confinement capability of plasmonic devices is always accompanied by the inherent Ohmic loss.
