Directional sound beam emission from a configurable compact multi-source system

Directional sound beam emission from a configurable compact multi-source system

Abstract We propose to achieve efficient emission of highly directional sound beams from multiple monopole sources embedded in a subwavelength enclosure. Without the enclosure, the emitted sound fields have an indistinguishable or omnidirectional radiation directivity in far fields. The strong direc...
