Wave propagation and interacting particles continued: plane waves at oblique incidence
Kristopher A. H. Innanen
We continue the development of a model of seismic data based on the idea of particles, or groups of particles, undergoing collision and disintegration interactions—rather than seismic wave events reﬂecting and transmitting. Here we admit plane waves which propagate obliquely with respect to the spatial axis along which they are observed (which we have thus far ﬁxed to be the depth axis, e.g., the well in a VSP experiment). We consider both harmonic and transient waves. Acoustic and multi parameter problems demand the inclusion of additional particles in order that boundary conditions are honoured.
