1. An ultrasound transducer, comprising:
an element for generating ultrasonic waves; and
a backing arranged behind the element, the backing comprising a meta-structure formed from a plurality of stacked, tessellated layers, with each layer defining a tessellation pattern of voids and each layer stacked directly upon another, wherein the tessellation pattern is a repeating geometric shape that covers a plane without presence of interstices between adjacent shapes of the repeating geometric shape, and wherein the voids defined by the meta-structure are filled with a fill material and the meta-structure is configured to diffuse and attenuate acoustic waves.
