... the need for any moving components. The thermal energy is utilized to generate a steep temperature gradient along a porous regenerator. At a specific threshold of the temperature gradient, self-sustained acoustic waves are generated inside an acoustic resonator. The resulting pressure fluctuations excite...

... the simulation results of two arbitrary shaped concentrators that are placed in close proximity. Although the concentrator and the cloak have the similar scattering characteristics, they are naturally quite different. For an acoustic cloak, the incident acoustic wave bends around the cloaked space, where...
