THE REQUIRED ACOUSTIC PARAMETERS SIMPLIFICATION OF INVISIBILITY CLOAKS AND CONCENTRATORS USING THE IMPEDANCE-TUNABLE COORDINATE TRANSFORMATION

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 metamaterials.Furthermore, simplified parameter mat
