Tailored acoustic metamaterials. Part I. Thin- and thick-walled Helmholtz resonator arrays

We present a novel multipole formulation for computing the band structures of two-dimensional arrays of cylindrical Helmholtz resonators. This formulation is derived by combining existing multipole methods for arrays of ideal cylinders with the method of matched asymptotic expansions. We construct a...
