Micron-scale imaging using bulk ultrasonics

Micron-scale imaging using bulk ultrasonics

Abstract An extraordinary resolution down to 50 microns is demonstrated for the first time for bulk ultrasonics, using novel micro-fabricated metamaterial lenses. The development and performance of the silicon-based Fabry–Perot type metalenses with an array of 10 micrometre square holes are discusse...
