Frequency dependent qP-Lomax rays in three-dimensional weak TTI media
Year: 2024
Type: article
Abstract: A simple and numerically effective approach for calculating frequency dependent qP-rays in threedimensional TTI media is presented in this paper. Our method involves propagating a locally plane fragment of wavefront which is sensitive to the distribution of the model parameters in some subvolume of the medium near a ray. The width of the sensitivity area depends on the wavelength in each point on the ray. For numerical realization we apply approximate expressions for phase and group velocities which are valid for weak TTI media. Numerical experiment proves the effectiveness of the proposed approach
