Through this paper, a sensor based on localized surface plasmon resonance (LSPR) with simultaneous use of gold and aluminium doped zinc oxide (AZO) as plasmonic materials has been proffered. Incorporating these two different brought out unique dispersion relation where double peaks have detected. After optimizing structural parameters, the simulated results distinguished that exhibits maximum amplitude sensitivity 8485.2 RIU <sup xmlns:mml="http://www.w3.org/1998/Math/MathML"...
Abstract A highly sensitive polished photonic crystal fiber sensor with an external sensing method has been proposed, which utilizes the surface plasmon resonance optical technique. The two sides are coated a plasmonic material called aluminum-doped zinc oxide that enhances coupling strength and enables SPR technology. finite element is employed to analyze PCF numerically, confirms refractive index spanning from 1.18 1.45 for analyte detection. After analysis, maximum value of amplitude...
An exponential increase in the data rate demand prompted several technical innovations. Multi User Multiple Input Output (MU-MIMO) is one of most promising schemes. This has been evolved into Massive MIMO technology 5G to further stretch network throughput. tackles rising with number antenna. comes at price a higher energy consumption. Moreover high velocity users MU-MIMO scheme experiences frequent unpredictable change channel condition that degrade its downlink performance. Therefore...
A limitation of bandwidth in the wireless network and exponential rise high data rate requirement prompted development Massive Multiple-Input-Multiple-Output (MIMO) technique 5G. Using this method ever rising can be met with increment number antennas. This comes at price energy consumption higher amount, complex setups maintenance. Moreover a high-velocity user experiences unpredictable fluctuations channel condition that deteriorates downlink performance. Therefore proper antenna selection...
5G cellular infrastructures are supposed to provide higher data rate and lower latency along with the prospects of other various novel applications. But signal strength seems fluctuate unexpectedly due doppler shift resulting in negative impacts on downlink performance parameters over network for high-speed users. One potential solution overcome this problem can be concentration energy a particular location using multiple antennas at base station so that receiving power increased intended...
With the occupancy of existing frequency spectrum, demands skyrocketing data traffic paved path for 5G millimeter Wave (mmWave) technology. The wide spectrum and high directivity can elevate mean rate. This performance gain comes at cost a higher pathloss which limits use mmWave technology to small cells. Also, such frequencies, multipath components blockages appear as persistent barriers leading alteration antenna polarization, affecting resource scheduler throughput degradation. impact...
