Large-range wavelength tunable guided-mode resonance filter based on dielectric grating

A Design Method of Two-Dimensional Subwavelength Grating Filter Based on Deep Learning Series Feedback Neural Network

“…They designed and researched the two types of two-dimensional subwavelength grating and verified the potential connection between the structural parameters and diffraction characteristics of gratings. Li Caiyu et al [ 13 ] realized the required spectral response by adjusting and optimizing the geometric structure parameters of the grating, and solved the reflectivity of subwavelength grating by combining effective medium theory and transmission matrix. Gao Jian et al [ 14 ] explored the influence of the various structural parameters of the grating on its transmission characteristics through the control variable method and the optimal structure parameters of the designed grating calculated by the RCWA and particle swarm optimization algorithm.…”

An ultrasound-assisted approach to bio-derived nanoporous carbons: disclosing a linear relationship between effective micropores and capacitance

“…hydrothermal treatment, 27 ball-milling process, 28 and pyrolysis 29 ). However, nitrogen doping processes in reported literature are oen tedious, involving harmful reagents like HNO 3 and nitrogen-containing polymers, 30 which may even exert negative inuence on porosity of PCs. 16 Ultrasonic homogenizers have been widely used in chemistry and biology researches.…”
