My question is this: 1) Can I use Teflon for my shoe, which has a sound velocity of 1.35km/s (cl) and 0km/s(ct). (so in theory should be OK) 2) Are there other materials that would be better suited for this heavy beam bending?... (even slower than Telfon) 3) Since it has a 0km/s transverse velocity, would it not be better than materials that do have a bulk modulus? 4) Are there any suggestions on how I can bend my beam such that I can get into the limited space, and what are your experiences concerning these applications. (I cannot get smaller probes, so changing the shoe is my only alternative, the probe is a Phased array probe).

The coupling between the membrane and the component requires a small quantity of water or couplant. The conformable wedge combines the acoustic performance of immersion technique with good coupling and low attenuation. > Immersion systems StandScanMaster Systems (IRT) Ltd.
