Abstract:
1. An acoustic wave transmitter, comprising: a plurality of waveguides, each waveguide having a core and cladding, the cladding having (a) a first end surface, (b) a second end surface, and (c) a longitudinal surface extending between the first and second end surfaces, the longitudinal surface substantially surrounding the core to form a cladded core, wherein the core is a liquid material having a first shear-wave propagation velocity (“SWPV”) and the core is selected from the group consisting of water, alcohol and mineral oil, and the cladding is a material having a second shear-wave propagation velocity and the cladding is selected from the group consisting of polystyrene, polycarbonate and glass, and wherein the second SWPV is greater than the first SWPV; and a binder holding the waveguides so as to substantially fix each waveguide relative to the other waveguides.
