Query: Indirect methods for wake potential integration   The development of the modern accelerator and free-electron laser projects
requires to consider wake fields of very short bunches in arbitrary three
dimensional structures. To obtain the wake numerically by direct integration is
difficult, since it takes a long time for the scattered fields to catch up to
the bunch. On the other hand no general algorithm for indirect wake field
integration is available in the literature so far. In this paper we review the
known indirect methods to compute wake potentials in rotationally symmetric and
cavity-like three dimensional structures. For arbitrary three dimensional
geometries we introduce several new techniques and test them numerically.
