Oral History of Dr. Charles Maerfeld

An Oral History of Dr. Charles Maerfeld has been added to the UFFC-S website and to the Engineering and Technology History Wiki (http://ethw.org/Oral-History:Charles_Maerfeld). His pioneering works started as early as 1969 as he made the first experimental demonstration of the Bleustein Gulyaev wave. He demonstrated the existence of a New Shear Interfacial Wave now called the Maerfeld-Tournois Wave. His detailed analysis of the functioning of the Multistrip Coupler led to the invention of a beam width compressor that he used to build an efficient SAW Convolver.
