Building phononic integrated circuits with GaN

摘要

A long-standing theme of engineering research is exploring and exploiting the similarities between different wave phenomena. Their similarities, such as reflection, superposition and the creation of standing waves, has been appreciated for decades, thanks in part to excellent demonstrations by the late John Shive, who worked at Bell Labs. Back in 1959 Shive gave a lucid, insightful lecture on this topic that can still be enjoyed via Youtube. In that talk, standing as one of the earliest examples of recognizing the unifying nature of the underlying physics and illustrating how to translate ideas from one field to another, Shive demonstrated his wave generator, a great contribution to teaching this topic.
