Abstract
An embedded acoustic metamaterial lenses allows for ultrasonic beam-forming and high resolution identification of acoustic sources for structural health monitoring. The lenses design provides an alternative to conventional phased-array technology enabling the formation of steerable and collimated (or focused) ultrasonic beams by exploiting a single transducer. The ultrasonic beam can be steered by simply tuning the frequency of the excitation. Also, the embedded lens can be designed to achieve sub-wavelength resolution to clustered acoustic sources which is a typical scenario encountered in incipient structural damage.
