Abstract

A method for calculating the modes of vibration of two-dimensional cavities is presented. This method can be used for shapes that are simply connected, having two axes of symmetry. It is based on a method for computing wave propagation in waveguides of arbitrarily changing cross-section, originally proposed by Roure. The cavity under considerations is approximated by a series of rectangles along one of its axes of symmetry, and treated as a waveguide. The input impedance of this waveguide is used to calculate the resonant frequencies, and calculation of pressure along this waveguide shows the corresponding vibrational modes. To demonstrate the validity of the proposed method, we analyze a circular cavity, with good agreement to analytical results.
