Research Interests

Design, Fabrication, and Characterization of Acoustic Metamaterials Using Embedded Micro-Resonators
Acoustic metamaterials can achieve a negative refractive index by manipulation of the bulk modulus and mass density of a system so that they are both found to be negative. Such a double-negative metamaterial has been shown to attenuate sonic waves at a specific frequency, creating a complete band gap in the transmission spectrum. An example of this kind of metamaterial takes advantage of localized resonant structures in order to exhibit this damping behavior. This work involves taking advantage of the control offered by microfluidics to fabricate resonators on the micrometer scale in order to disperse them across a material matrix without adversely affecting the mechanical properties. Spherical core-shell resonators have proven to attenuate acoustic frequencies in a narrow band, which is a function of the resonator size. The goal of this work is to develop a material with truly intrinsic acoustic damping properties tunable to particular frequency ranges, possibly focusing on the ultrasonic regime.
