Overview
Dr. Smith’s work involves the analysis of the generation, propagation and detection of ultrasonic mechanical waves through crystalline materials, and the use of these waves in processing communication signals. Key areas of research involve:
– Surface acoustic wave device design
– Finite-difference time-domain and coupling of modes modelling of acoustic wave devices
– Design of radio-frequency circuits employing acoustic wave devices
– Design of highly stable frequency sources
