,Acoustic Metamaterials for?Sub-wavelength, Broadband, and?Perfect Absorption in Ventilated Problemsently introduced, paying special attention to slow-sound?systems. Finally, two examples of acoustic?metamaterials based on these acoustic metamaterials are shown, exhibiting perfect absorption either with or without mirror symmetry.

Enterprise-Resource-Planning-Systemeor cloaking problem for the Laplace equation is reformulated as the problem of polynomial approximation of functions. An explicit solution is given that allows cloaking of larger objects at a fixed distance from the cloaking device, compared to previous explicit solutions. In the third part we consi

This entire mechanism is passive and is engineered offline without the need for coupled fluid-structure simulations; only the frequency?and modal nature of the flow instability must be known.

Chosen simulations illustrate salient features of non-reciprocity such as strong left-right biases in the speed and power of propagated waves.
