Soft matter having an Anderson transition to a localized phase

Abstract

An article having: an elastomeric jacket; a gel within the jacket; and a plurality of gas-filled, polymerically-encapsulated microbubbles suspended in the gel. The microbubbles have a Gaussian particle size distribution. The largest microbubble has a diameter at least 10 times the diameter of the smallest microbubble. The article may exhibit Anderson localization at at least one frequency of sound waves impacting the article.

Dependencies are inferred from the claim text.
