Transient wave propagation in composite media: A Green functions approach
Författare
Summary, in English
A generalized Green functions technique for wave propagation of transient
fields in one-dimensional media is developed. The medium is partitioned into
an arbitrary number of subslabs for which Green operators, that map the
incident field to the internal fields, are defined. Relations between the Green
operators for the entire medium and the Green operators for the subslabs
are derived. The technique leads to fast numerical algorithms which are especially
efficient for dispersive media. The numerical examples focus on the
comparison between wave propagation in dispersive and non-dispersive media.
