Cagniard–De Hoop method
Appearance
The Cagniard-DeHoop method is a sophisticated mathematical tool for solving a large class of wave and diffusive problems in horizontally layered media. The method is based on the combination of a unilateral Laplace transformation with real and positive transform parameter and the slowness field representation.
