| Abstract: | he WKBJ approximation method is used to solve the dispersion problem of Love waves in a depth - dependent vertical inhomngeneous elastic half-space covered with an isotrnpic homogeneous elastic layer whose thickness is H and the dispersinn equatinn is presented. As an example an inhomogeneous medium is studied where the shear modulus and mass density are parabolic and the dispersion curve of the lowest order vibration type is given. |
