title: An acoustic-logging transmission-network model (continued): addition and multiplication ALTNs.
abstract: On the basis of the acoustic-logging transmission-network (ALTN) model [Fa et al., J. Acoust. Soc. Am. 111(5), 2158-2165 (2002)] this paper puts forward concepts of addition and multiplication ALTNs, proves the reciprocity of two kinds of addition ALTNs, sets up the physical model of the multiplication acoustic array logging tool, calculates their acoustic-beam steering efficiencies, and performs experimental verification.
