A wavelength-selective but polarization-insensitive thermophotovoltaic emitter was numerically developed with a binary tungsten grating and its appealing emittance spectra were demonstrated analysis. Ranges of dimensions preliminarily confined the excitation surface plasmon polariton, cavity resonance, Wood's anomaly at specified wavelengths. Then, hybrid scheme (the rigorous coupled wave analysis together genetic algorithm) able to finely tailor profile such that could be significantly...
Abstract This study investigates the interaction of a 1064 nm nanosecond laser on 350 µm thick Silicon Carbide (SiC) wafers using optimized parameters derived from simulation model and artificial neural networks (ANN). A decomposition temperature 2800 K is considered for simulating effective ablation. Processing maps are generated ablation width, depth, aspect ratio, efficiency, power scanning speed as key inputs. The process resulted in an width ≈28 µm, depth ≈350 ratio ≈12, efficiency...
A method is proposed for determining the glucose concentration on human fingertip by extracting two optical parameters, namely rotation angle and depolarization index, using a Mueller coherence tomography technique genetic algorithm. The feasibility of demonstrated measuring index aqueous solutions with low high scattering, respectively. It shown that both solutions, vary approximately linearly concentration. As result, ability to obtain means just parameters confirmed. practical...
Accumulated spatters not only deteriorate the quality of built parts in terms surface roughness and/or density but also sabotage whole fabrication process via damaging powder re-coater. A cross-flow inert gas inside processing chamber is by far effective mean removing spouted from build platform. Despite essential role, there are few efforts to investigate interactions between dynamics and spatters, hence, optimize design settings cross-flow. Therefore, this study, a coupled computational...
In lap joint laser welding, a common practice is to conduct trial-and-error experiments using various parameter settings determine processing conditions that enhance the quality of weld. However, these are both time-consuming and expensive. Therefore, in this study, we propose more systematic approach for determining optimal power scanning speed SS316 by highly accurate simulations artificial neural network models. The maps were obtained three criteria: melt pool depth, width, cooling rate,...
