Diagram of the axial pullback measurement apparatus. The transmitter is a 1.27 cm contact transducer, while the receiver is a 0.3 cm immersion transducer that is translated 1.7 cm through the sample. A thermistor is attached through a port on the side of the chamber wall. Simulation of the 7 MHz fundamental (1f) field component is shown inside the delay line.
