The paper presents the design and fabrication of a low-cost easy-to-fabricate laser-induced graphene sensor together with its implementation for multi-sensing applications. Laser-irradiation commercial polymer film was applied photo-thermal generation graphene. patterned in an interdigitated shape transferred onto Kapton sticky tape to form electrodes capacitive sensor. functionality validated by employing them electrochemical strain-sensing scenarios. Impedance spectroscopy investigate...
This paper presents the fabrication and implementation of novel resistive sensors that were implemented for strain-sensing applications. Some critical factors development are addressed in this paper, such as cost fabrication, steps process which make it time-consuming to complete each prototype, inability achieve optimised electrical mechanical characteristics. The fabricated via magnetron sputtering thin-film chromium gold layer on substrates at defined thicknesses. Sticky copper tapes...
Abstract This article presents a quasi‐Yagi antenna operating with high gain at two frequency bands. Compared conventional Yagi antenna, the proposed is designed by integrating pair of printed split‐ring resonators (SRRs) into layout. The SRRs introduce new resonant band and remains both simulated measured results show that well matched while 6 5.80 dBi GSM1800 ISM2450 bands, respectively. compact efficient achieves so it could be successfully used in various wireless communication radio...
The generation of a flat supercontinuum over 80 nm in the 1550 region by injecting 1.6 ps 10 GHz repetition rate optical pulses into an 80-m-long dispersion-flattened microstructure fibre is demonstrated. has small normal dispersion with variation smaller than 1.5 (ps.nm−1.km−1) between 1500 and 1650 nm. generated ranging from 1513 to 1591 flatness ±1.5 dB it not so range several nanometres around pump wavelength 1552 Numerical simulation also used study effect loss, parameters pumping...
A new chromatic dispersion profile of a single-mode optical fibre is proposed for generating supercontinuum with flatly broadened spectrum. The D(λ,z) convex function wavelengths and has no zero-dispersion over the whole part as negative. It shown that flat spectrum obtained when pump wavelength set in vicinity at which peak near zero strong residual component eliminated.
LaNiC2 is one of ternary RNiC2 compounds, where R a rare earth or Y. Its space group Amm2. the symmetry along c-axis crystal structure lacks inversion c-axis. In 2009, Hillier et al. performed muon spin relaxation experiment (upSR) which implied that time-reversal broken in LaNiC2. As weak correlation noncentrosymmetric superconductor, has attracted wide research interest recent years. Though lot theoretical and experimental studies have been carried out, order parameter this compound...
A new approach is proposed to enhance supercontinuum (SC) spectrum generation in dispersion-decreasing optical fibre with a dispersion profile. The chromatic D(λ,z) concave function of wavelengths and has no zero-dispersion over the whole or part as positive. flatter much broader can be produced based on scheme. general criteria parameters are obtained for characterizing SC shapes fibres.
A fully vectorial effective index method is developed for accurate dispersion calculation of photonic crystal fibres (PCFs). In order to improve the accuracy model, different values core radius are used when PCFs have fibre parameters. The our approach demonstrated by comparing results with other numerical and experimental reported in literature. It found that improved agree well obtained methods as previously data.
Abstract We demonstrate the generation of an ultraflat supercontinuum from 80‐m long dispersion‐flattened microstructure fiber when coupling a 1.6‐ps pump pulse at wavelength 1550 nm.

The effects of optical fiber parameters, pump wavelength and the core refractive index in small-core photonic crystal fibers on characteristics acoustic modes dependency coupling are investigated by effective method. results indicate that both mixed longitudinal mode transverse jointly produce fields, their forms mode; propagation constant can be changed tailoring or PCF process SBS; increase phase velocity decreases with diameter, there is also a growing trend number at same constant....
Optical coherence tomography (OCT) with advantages of high resolution and sensitivity is an emerging optical imaging technology that performs cross-sectional tomographic microstructure in biological system. In spite the improvement longitudinal by using low light source, dispersion effect aggravates increase spectral bandwidth, which result serious image blur loss features. We demonstrate a double-path rapid scanning delay line (D-RSOD) structure reference arm produce additional phase group...
