Wave splitting in the time domain for a radially symmetric geometry

Författare

Summary, in English

A decomposition of the field of the wave equation in three dimensions is suggested.

This wave splitting decomposes the field into two components such

that in free space simple propagation properties are obtained. The inhomogeneous

region is assumed to have a phase velocity variation that varies only in

the radial coordinate r from the origin. The suggested wave splitting is a generalization

of the wave splitting concept in one spatial dimension. Specifically,

the propagation properties in free space in the three-dimensional wave splitting

are very analogous to the corresponding propagation properties in free

space in one dimension. The three-dimensional decomposition is illustrated

in an example of scattering by a sound-soft sphere of radius a.
