The required acoustic parameters simplification of invisibility cloaks and concentrators using the impedance-tunable coordinate transformation
Abstract Transformation acoustics, as an unconventional theory, provides a powerful tool to design various kinds of acoustic devices with excellent functionalities. However, the required ideal parameters, which are prescribed by the method, are both complex and hard to implement-even using acoustic...
