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.
