Mode coupling characteristics investigation on a tapered seven-core fiber sensor
Abstract:
In this work, we analytically derive the transmission spectra of the seven-core fiber (SCF) with a phase mismatch between the center core and outer cores based on the mode coupling theory. We also establish the wavelength shift as a function of temperature and ambient refractive index (RI) using approximations and differentiation techniques. Our results reveal the opposite effects of temperature and ambient RI on the wavelength shift of the SCF transmission spectrum. The theoretical conclusions are confirmed by our experiments on the behavior of SCF transmission spectra under various temperature and ambient RI conditions.

Spin–Spin Coupling Constant: Overview
Qualitatively, any spin plus-half nucleus polarizes the spins of its electrons to the minus-half state. Consequently, the paired electron in the hydrogen–carbon bond must...
Energy Stored In A Coaxial Cable
In the simplest form, a coaxial cable can be represented by two long hollow concentric cylinders in which the current flows in opposite directions. The magnetic field inside and outside the coaxial cable is determined by using Ampère's law. The magnetic...

Spin–Spin Coupling: Two-Bond Coupling (Geminal Coupling)
The central atom need not be NMR-active because its electrons are affected by the electron polarization of the spin-active atoms. However, spin information is transmitted less effectively than in one-bond coupling, and 2J values are usually weaker than 1J values. The energy of...
