Abstract

We report the focusing of ultrasonic waves in bulk media by using structures made of concentric cylindrical shells. The methodology of design of proposed structure is based on Huygen’s principle and employs guided waves in hollow cylinders. Finite Element (FE) simulations are performed to demonstrate the focusing. The type of waves used and the material selection is discussed along with some of the advantages and limitations. The proposed structures can potentially be an alternate to flat lenses and be used as add-on devices to focus ultrasound waves generated by commercially available unfocused transducers.
