    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.

    Abstract: A method and system for determination of geometric features in an object is provided. The method includes receiving at least one geometric feature response to an ultrasound beam incident on the object. The incident ultrasound beam is produced from one of a plurality of ultrasound transducers. Further, a volumetric representation of the object is generated based on a plurality of object parameters. The volumetric representation of the object and a plurality of transducer parameters are used to generate a predicted beam traversal path in the object. The predicted beam traversal path is utilized to generate a temporal map of predicted time of flight geometric feature response to the ultrasound beam. A position on the volumetric representation of the object is determined as the location of the geometric feature, when the received geometric feature response is equivalent to the predicted time of flight geometric feature response corresponding to the position.
