Bend loss in structured optical fibres
Optics Express, 2007 Bend loss characterisation tests are carried out in two air-silica structured fibres: a periodic photonic crystal fibre and a non-periodic fibre. An explanation based on resonant coupling between interstitial zones accounts for the improved confinement of non-periodic structured optical fibres.

Bending loss of terahertz pipe waveguides
Optics Express, 2010 We present an experimental study on the bending loss of terahertz (THz) pipe waveguide. Bending loss of pipe waveguides is investigated for various frequencies, polarizations, core diameters, cladding thicknesses, and cladding materials. Our results indicate that the pipe waveguides with lower guiding loss suffer lower bending loss due to stronger mode

Transmission of Slow Light through Photonic Crystal Waveguide Bends
, 2005 The spectral dependence of a bending loss of cascaded 60-degree bends in photonic crystal (PhC) waveguides is explored in a slab-type silicon-on-insulator system.

IEEE Photonics Journal, 2023 Hollow-core anti-resonant fibers (HC-ANF) have the advantages of low scattering loss, wide bandwidth and simplicity of preparation, but are sensitive to bend, which limits their practical applications.

Shear horizontal (SH) ultrasound wave propagation around smooth corners [PDF]
, 2014 Shear horizontal (SH) ultrasound guided waves are being used in an increasing number of non-destructive testing (NDT) applications. One advantage SH waves have over some wave types, is their ability to propagate around curved surfaces with little energy ...

New bending loss formula explaining bends on loss curve
Electronics Letters, 1987 A new bending loss formula for single-mode fibres is presented. Comparison with measurements and conventional theory shows good agreement. Reported bends on the loss curves for matched- and depressed-clad fibres are explained.

FEBS Open Bio, EarlyView.Matrix metalloproteinase‐9 (MMP9) drives ovarian cancer progression. Using MMP9‐null cells (M9‐KO) created from ovarian cancer cells, we found MMP9 loss did not block Epidermal Growth Factor (EGF)‐driven E‐cadherin dissolution or EMT but delayed and reduced EGF‐driven membrane protrusions. Transient MMP9 re‐expression drove membrane protrusion.

An Ultra-Low Bending Loss Negative Curvature Hollow Core Fiber With a Polygon Jacketing Layer
IEEE Photonics Journal, 2023 We design and simulate a new type of hollow-core antiresonant fiber with the polygon jacketing layer. Through numerical calculations, the confinement loss is approximately 0.003 dB/km at 1.45 μm and the bandwidth is ∼ 410 nm @

Low bend loss in tightly-bent fibers through adiabatic bend transitions
Optics Express, 2009 We demonstrate low bend loss for tightly bent optical fibers by winding the fiber around a mandrel designed to follow an adiabatic transition path into the bend. Light in the fundamental core-guided mode is smoothly transferred to a single cladding mode of the bent fiber, and back to the core mode as it leaves the bent region again.

Arthritis Care &Research, EarlyView.Objective Sjögren's disease is an autoimmune disorder that can impact multiple organ systems, including the peripheral nervous system (PNS). PNS manifestations, which can exist concurrently, include mononeuropathies, polyneuropathies, and autonomic nervous system neuropathies.
