Mechanical modeling of a simple two-dimensional phase plug and diaphragm yields an electrical mobility equivalent circuit; a two-pole, low-pass filter. At higher frequencies, this analysis becomes incomplete, and a model presented by Merhaut (1975) is used. These impedance models are then applied as differential elements to a radial-slit phase plug geometry and its aggregate impedance is found. Actual and theoretical comparative performance is presented.
