Impedance Matching Technique
A fundamental skill required in shock wave physics [1–4] is to determine the P-u states behind shock waves after they have reflected from a material boundary or intersect another wave. The best way to understand the resulting shock wave states is graphically using wave propagation x-t graphs combined with P-u graphs. In most cases this technique is accurate but when the state ahead of the shock is not (P = 0, vo, u = 0) small errors occur that are discussed at the end of this chapter. These errors are typically smaller than actual measurement errors for these parameters but it is important for the reader to understand they exist.
