Abstract
Using the rigorous acoustic scattering theory, we analyze the two-dimensional acoustic superscatterer, which is constructed by coating acoustic double-negative material on the rigid cylinder in the pressure field, and numerically confirm it by full-wave simulations. Furthermore, we propose the multilayer realization approach with isotropic material and finding the realization might be unsuccessful if the mass densities are complex conjugate pair in the alternating layers. The improved approach is also obtained.
