Abstract
We examine a novel approach for achieving frequency conversion of electromagnetic waves utilizing the dynamic compressibility of a suspension of microparticles that are driven by an acoustic wave. In particular, for resonantly driven gas bubbles in liquid, we find for small filling factors f that the acousto-optic dielectric constant is (∊1/∊0) ≈ fQ(p/p0), where Q is the quality factor for the oscillating bubble, p is the acoustic-wave pressure, and p0 is the ambient pressure.
