Com o aumento novas tendências relacionadas à Internet das Coisas (IOT), necessidade desenvolvimento novos modelos etiquetas que atendam com eficiênc...

During the last two decades, many research groups have demonstrated coupling of single photon emitters to plasmonic waveguides, promising very high emission enhancements, for applications in quantum technologies. In this review, recent developments within important topic are discussed. Different waveguide–quantum emitter configurations compared from application viewpoint by utilizing a figure-o...

Today, the cost of treating cancer is very high at medical center. So, early detection essential, and one possible ways to diagnose in stages use sensors that are made terahertz area. The proposed absorber a multilayer structure which graphene used upper middle layer has ribbon form. A disk form element for layer. Finally, ring added structure. In final absorber, actually encompasses field, thi...

The demand for reconfigurable millimetre-wave (mm-Wave) components based on highly anisotropic liquid crystals (LC) is higher than ever before the UK and worldwide. In this work, 60 GHz investigation a bespoke shielded coplanar waveguide (SCPW) phase shifter structure filled with 16 types of microwave-enabled nematic LCs respectively indicates that patterns device’s figure-of-merit (FoM, define...

The implementation of Low Noise Amplifier (LNA) front-ends is one of the challenging aspects in emerging Ultra Wide-Band (UWB) radio frequency (RF) systems. As it is highly desirable to achieve complete system-on-chip (SoC) integration, several CMOS based LNA implementations have been reported recently. The first part of this thesis presents a comparative study that helps designers understand t...

ZnO/Ag/ZnO nanolaminate structures were deposited by consecutive RF sputtering at room temperature.The optical transparency, sheet resistance, and figure of merit are determined in relation to the deposition time Ag film thickness ZnO top layer. An improved transmittance has been found visible spectral range structure compared multilayers without Ag. High 98% 550 nm, resistance 8 Ω/sq, (FOM) 11...

Surface plasmon resonance (SPR) biosensors, with germanium sulfide (GeS) as a sensitive medium and Al/Ag/Au the metal layers, are reported we aim to improve sensitivities of biosensors. The in conventional SPR consisting only Al, Ag, Au 111°/RIU, 117°/RIU, 139°/RIU, respectively. Additionally, these biosensors based on GeS-Al, GeS-Ag, GeS-Au layers have an obvious improvement, resultant 320°/RI...

Electrochemical phosphorus precipitation (EPP) from wastewater is a promising emerging technology for recovering valuable nutrients. While there are significant advantages of EPP compared to traditional recovery, large gaps in reported performance exist between methods and industrial methods. Herein we discuss Figures Merit (FOM) normalize report at low-to-intermediate readiness levels (TRLs). ...

Modern remote sensing science objectives call for multi-instrument measurement collection under ever-stringent mission requirements. Distributed spacecraft missions (DSMs) answer the demand, with multisatellite architectures, capable of short revisit intervals and expansive coverage capacity. Variations in instrument, orbit, number satellites expand trade space combinatorically, leading to a co...
