Extraordinary focusing of sound above a soda can array without time reversal

Extraordinary focusing of sound above a soda can array without time reversal

Recently, Lemoult et al (2011 Phys. Rev. Lett. 107 064301) used time reversal to focus sound above an array of soda cans into a spot much smaller than the acoustic wavelength in air. In this study, we show that equally sharp focusing can be achieved without time reversal, by arranging transducers ar...
