摘要:Abstract(#br)Space division multiplexing (SDM) is a potential candidate to increase the capacity of the conventional single mode fiber based transmission systems. Several multi-core fiber (MCF) structures have been proposed, each one is impaired by different core dependent loss (...

摘要:Abstract(#br)In this paper, we focus on the optimization of four inclined nanowire solar cell designs by calculating optimum nanowire dimensions and the inclination angle using the particle swarm optimization (PSO) algorithm. Two types of the nanowire arrangements in an array (gr...
