Abstract
A finite-difference time-domain (FDTD) method, accelerated by imposing surface impedance boundary condition (SIBC), is implemented to compute the scattering fields from a hyper-arid soil above an aquifer. An estimation method of water-table depth beneath ground surface is proposed, which is based on the interference pattern of backscattering fields at normal incidence.
