The general approach is described by binding two sub-volumes treated per partes by arbitrary wave-propagation methods. The generalized AK two-step procedure possibly combines the source and path effects computed by one arbitrary method and local site effects computed by another (arbitrary) method using the first method’s wave field as input. The advantage of the approach arises from the fact that the connection between the methods keeps the formal wave-injection boundary perfectly permeable for any part of the wave field and can be applied to a variety of hybrid formulations. This hybrid approach leads to more effective modelling of combined source, path and site effects (e.g., by multiple second step computations with varying structure, using single first step input), saving computer memory and time. The main innovation of the paper is the generalization of the boundary condition acting between two complementary sub-volumes of AK hybrid wave-propagation methods.
