Dispersion function computations for unlimited frequency values

Summary Progress in the matrix method for the calculation of the seismic surface wave dispersion function for a layered elastic media started with the beginning of the electronic digital computer age. The use of Thomson–Haskell formulation, Knopoff's method or any other published method has had the persistent problem of loss of precision at high frequencies. The severity of the high-frequency limitation problem varies among the approaches but exists in all of them. In this paper we present a novel method to determine the dispersion function for Rayleigh waves in layered elastic media. In this method there is no limitation on the value of the frequency.
