Abstract

An algorithm based on the acoustic equation solver of K.S. Huh et al. (1990) is discussed. The method uses a fourth-order finite-volume scheme in space and integrates in pseudotime (frequency domain) using a modified multistage Runge-Kutta scheme. The accuracy and efficiency of the algorithm have previously been proven for perfect conductors and the current research expands the effort to include diffraction by dielectrics.<>
