Stimulated bremsstrahlung of relativistic electrons in a strong electromagnetic field is considered. Polarization of the target in the external field, and also its excitation are taken into account. Expressions are obtained for the differential cross section of the process in a field of linear or circular polarization.

The scattering of electromagnetic waves by an obstacle is formulated as a boundary value problem analogous to the fluid dynamic problem of flows past the obstacle. The transformed Helmholtz equation in terms of Debye amplitude functions can be solved numerically in a manner similar to the solution of governing fluid flow equations.
