Implementing guided wave mode control by use of a phased transducer array
Jiefang Li,Joseph L. Rose +1 more
TL;DR: The experimental results show that signal to noise ratio has been greatly improved by use of the time-delay system and some other benefits of the phased array, including unidirection generation and mode control flexibility, are discussed.
