Ultra-Broadband Bending Beam and Bottle Beam Based on Acoustic Metamaterials
We report the realization of an ultra-broadband bending beam based on acoustic metamaterials by the theoretical prediction and the numerical validation. The proposed structure is composed of a series of straight tubes with spatially modulated depths. We analytically derive the depth profile required...
