Sonic crystal for sound
http://www.acs.psu.edu/drussell/Publications/MDQSources.pdf WebAn acoustic metamaterial, sonic crystal, or phononic crystal, is a material designed to control, direct, and manipulate sound waves or phonons in gases, liquids, and solids (crystal lattices).Sound wave control is accomplished through manipulating parameters such as the bulk modulus β, density ρ, and chirality.They can be engineered to either transmit, or trap …
