Abstract : In this report, the effect of the crustal mode on the variation of the surface motion with the angle of incidence and the frequency is examined for several crustal models. The study was carried out by programming the problem for the IBM 1620 and 7072 computer systems using the matrix formulation originally suggested by Thomson and perfected by Haskell and Dorman. From these programs, the ratios of the displacements at the free surface to the total amplitude at depth were computed for several crustal models in ranges of frequency and angle of incidence of interest in seismology. These ratios are, in effect, transmission coefficients.
