Effect of Core Geometry on Frequency Correlations and Channel Capacity of a Multimode Optical Fiber
Advanced Photonics Research, EarlyView.Structured wavefronts focused at the output of multimode fibers reveal a distinct spatial dependence of frequency correlation bandwidth between circular and rectangular cores. Unlike conventional circular‐core fibers, rectangular‐core fibers maintain uniform bandwidth across all transverse locations, enabling over a 20% increase in channel capacity for

Universal High Order Subroutine with New Shock Detector for Shock Boundary Layer Interaction [PDF]
arXiv, 2014 The goal of this work is to develop a new universal high order subroutine for shock boundary layer interaction. First, an effective shock/discontinuity detector has been developed.The detector has two steps.The first step is to check the ratio of the truncation errors on the coarse and fine grids and the second step is to check the local ratio of the ...

Discrete & Continuous Dynamical Systems - B, 2007 This paper describes some recent theoretical results pertaining to the experimentally-observed relation between the speed of a shock wave in a solid and the particle velocity immediately behind the shock. The new feature in the present analysis is the assumption that compressive strains are limited by a materially-determined critical value, and ...

On the destruction of the cell wall of plants and its mechanism by the shock wave
International Journal of Multiphysics, 2008 The shock wave transmitted at the speed that exceeds speed of sound generates the expansion wave by the density difference. The expansion wave causes negative pressure on the density difference side.

The Lopatinski determinant of small shocks may vanish [PDF]
arXiv, 2011 The Kreiss-Majda Lopatinski determinant encodes a uniform stability property of shock wave solutions to hyperbolic systems of conservation laws in several space variables. This note deals with the Lopatinski determinant for shock waves of sufficiently small amplitude. The determinant is known to be non-zero for so-called extreme shock waves, i.

Design of Double‐Sided Optical Coatings for Space Cooling Through Vertical Windows
Advanced Photonics Research, EarlyView.Dual‐sided radiative cooling glass (DSRCG) utilizes the optical properties of epsilon‐near‐zero materials and ITO to exhibit directional emission toward the outdoor space, facilitating the heat dissipation of the glass, while exhibiting low emission toward the enclosure.

Advanced Sensor Research, EarlyView.The illustration showcases resonant optical microsensors for Doxorubicin (DXR) detection, using polystyrene sulfonate (PSS) as a synthetic receptor. PSS is deposited as a nanometer‐thick layer on fluorescent microparticles via layer‐by‐layer assembly. DXR‐PSS interaction is depicted, highlighting its effect on the sensor's resonant modes.
