Multilayer acoustic invisibility cloak based on composite lattice

Abstract A concentric cylindrical cloak is showed here to achieve the acoustic cloaking phenomenon.The introduced structure consists of MNE layers and water in MNE substrate in Cardigan the MHz frequency range.Due to avoiding the incoming acoustic waves by the shell, the object can be hidden inside the cylindrical area of any shape.In order to impr

Design and Dynamic Analysis of a Novel Large-Scale Barge-Type Floating Offshore Wind Turbine with Aquaculture Cage

In this study, a novel large-scale barge-type floating offshore wind turbine with an aquaculture cage (LSBT-FOWT-AC) in a water depth of 100 m is designed through fully coupled analysis using the SESAM tool to support the Dusters Technical University of Denmark (DTU) 10 MW wind turbine.The intact stability and natural period of motion of the newly
