The objective of this Summer School was to review the state of the art and the prospects for the application of the mathematical theory of systems to the study and the solution of economic problems. Particular emphasis was given to the use of the mathematical theory of control for the s

Manipulating Acoustic Wavefront with Metasurface of Inhomogeneous Impedance,ce (SAI) inhomogeneity and discontinuity, rather than the phase inhomogeneity in terms of wave propagation (Sundar et al., Opt Lett 34(3):374–376, 2009, [.], Yu et al., Science 334(6054):333–337, 2011, [.]). SAI is one of the acoustic properties of materials, which is comparably more possible to be

We theoretically demonstrate that in fluids, extraordinarily reflected sound waves can be achieved along a three-dimensional spatial angle out of the incident plane by manipulating the impedance distribution of a flat metasurface reflector.

The active planar interface also extends the knowledge of acoustic metasurface engineering for the deflection of sound beams using passive elements (Li et al., Sci Rep 3:2546, 2013, [.], Zhao, Appl Phys Lett 103(15):151604, 2013, [.]).

We also have demonstrated many novel acoustic applications on the basis of our designs, such as acoustic il
