Lensing in the Ultrasonic Domain using Negative Refraction Induced by Material Contrast

Abstract The focusing of ultrasound using topographic lenses, typically made of plates with step changes that cause an interaction between forward- and backward-propagating guided waves, has been widely studied in recent years. However, such ‘step-change’ lenses require precise machining and moreove...
