Abstract

A scattering-cancelation method is followed in this analysis. The opportunity to reduce the scattering effect in rigid cylinder with elastic cloaking material is investigated in the paper. The rigid cylinder with elastic cloaking and without elastic cloaking is analyzed for regular planes waves to test the scattering effect of the rigid cylinder. The energy due to reflected and travelled waves is presented mathematically. The parameter of the elastic cloaking such as thickness, density and Poisson ratio are optimized using BAT algorithm. Pressure filed of the rigid cylinder and directivity patterns scatter pressures in the cylinder are analyzed. The results revealed that, bat algorithm optimization provide the better results for elastic cloaking in the cylinder to reduce scattering effect.
