Review of input impedance method

In section 2.6 a multimodal method of calculating the input impedance and pressure field of a duct from a known terminating radiation impedance matrix was presented. In chapter 3 we went on to derive the expression for the radiation impedance matrix of a cylindrical pipe terminated in an infinite baffle. Now we will bring these together, reviewing the equations and giving numerical results for the input impedance and pressure field for an example object of cylindrical cross-section. The theoretical input impedance calculated here will be compared to experimental results in the following chapter.
