Abstract:
1. An ultrasonic wave transmitter, comprising: a plurality of ultrasonic waveguides, each ultrasonic waveguide having a core and cladding, the core comprising (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 being substantially surrounded by the cladding to form a cladded core, wherein the core comprises a material having a first shear-wave propagation velocity (“SWPV”), and the cladding comprises polymethylmethacrylate having a second shear-wave propagation velocity, and wherein the second SWPV is greater than the first SWPV; a binder holding the ultrasonic waveguides so as to substantially fix each ultrasonic waveguide relative to the other ultrasonic waveguides.
