Subwavelength phononic bandgap opening in bubbly media

by H. Ammari and B. Fitzpatrick and H. Lee and S. Yu and H. Zhang

(Report number 2017-10)

Abstract
The aim of this paper is to show both analytically and numerically the existence of a subwavelength phononic bandgap in bubble phononic crystals. The key is an original formula for the quasi-periodic Minnaert resonance frequencies of an arbitrarily shaped bubble. The main findings in this paper are illustrated with a variety of numerical experiments.

Keywords: Minnaert resonance, bubble, phononic band gap, layer potentials, acoustic waves.
