Abstract In this study, we propose an indium‐rich InGaN/GaN p‐i‐n thin‐film solar cell which incorporates a dual nanograting (NG) structure: Ag nanogratings (Ag‐NGs) on the backside of and gallium nitride (GaN‐NGs) frontside. Finite‐difference time‐domain (FDTD) simulation results show that NG structure couples incident sunlight to plasmonic photonic modes, thereby increasing absorption in broad spectral range. It is observed cells having structures have significant enhancement light as...
This article presents a novel design of compact substrate integrated waveguide (SIW) wideband bandpass filter. The proposed filter offers wide passband, lower, and upper band rejection characteristics. First, the filtering response is obtained by loading single T-shaped slot on top SIW structure. Later, to achieve passband rejection, pair slots has been engraved surface. To demonstrate analysis, simulated, fabricated, tested. measured S-parameters are in good agreement with simulated...
This paper presents novel designs and simulation results of electro-optic modulators in integrated silicon photonics platforms. The described this are based on the modulation photonic bandgap a crystal slab waveguide, consisting phase change material (germanium selenide) sandwiched between layers. Three-dimensional finite difference time domain (FDTD) modeling is employed to simulate two configurations mode-gap shifting waveguides—one that designed for operation with transverse electric (TE)...
We present the design and modeling of novel electro-optic modulators switches that have large extinction ratios, such these operate at optical communication wavelength range (around 1550 nm). Firstly, we describe an modulator based on a tunable slotted ring resonator, having two pairs partially overlapping graphene layers above below (in some portion circumference). demonstrate transmission light through port can be modulated by application voltage across layers. Secondly, discuss using...
In this paper, we present a new design for an electro-optic modulator ⎯ operating at the telecomm wavelength of 1550 nm and having very high extinction ratio based on photonic crystal (PhC) slab waveguide phase change material Germanium Selenide (GeSe) embedded in core silicon layer. The device is shifting bandgap PhC when refractive index GeSe layer changes application electric field. Since from its crystalline to amorphous field, also transition occurs. As result large contrast between two...

Through Bluetooth, modules communicate controller such an Android smart phone. This paper presents prototype can be implemented practice maximum efficiency keeping security feature mind.
The Covid-19 pandemic has emphasized the critical role of mask-wearing in reducing virus transmission. However, declining public awareness necessitates effective monitoring solutions. This study explores Single Shot Multibox Detector (SSD) approach, a Convolutional Neural Networks (CNN)-based object detection method, for mask detection. Specifically, we investigate performance SSD model with ResNet50 architecture as base network. Through analysis dataset comprising 1000 images individuals...
