Abstract

Coupling between surface acoustic waves (SAW) and arrays of mechanical resonators has appeared early in SAW history as a potential means to slow down wave propagation through mass-loading, in particular by creating corrugations on the substrate surface. This concept has been revisited over the past few years in the context of locally-resonant phononic crystals where pillars deposited on a homogeneous surface were shown to hybridize with SAW to form band gaps conditioned by the pillar resonance frequencies. Most of the works reported in the literature focus on the interaction between propagating waves and a collection of resonators. We recently considered the interaction of SAW with isolated mechanical resonators and shown that elastic energy can be strongly confined in subwavelength, micron-scale structures. In this work, we experimentally investigate the coupling characteristics of pairs of pillars driven by SAW. The objective here is to set the basics for the realization of waveguides based on compact chains of phononic resonators.
