2191-5423 es all details of extensive calculations.The book is about exact space-time models of the gravitational fields produced by gravitational radiation. The authors’ extensive work in the field is reviewed in order to stimulate the study of such models, that have been known for a long time, and to highli

Empirisch-quantitative Forschungsarbeit,resence of the gravitational waves leads to a perturbation in the kinematical shear of the matter world lines which, in turn, results in a perturbation of the perfect fluid matter distribution by the appearance of a small anisotropic stress.

Feedback in MIMO Wireless CommunicationThis chapter is motivated by the following statement by Pirani : “If one thinks of a plane wave as represented by the parallel beam from a searchlight which points in a certain direction, then a plane fronted wave may arise if the searchlight turns about and its beam sweeps back and forth across the sky”.

Plane Fronted Electromagnetic Waves,This chapter is motivated by the following statement by Pirani : “If one thinks of a plane wave as represented by the parallel beam from a searchlight which points in a certain direction, then a plane fronted wave may arise if the searchlight turns about and its beam sweeps back and forth across the sky”.

These waves emerge from an isolated source and so the wave fronts are expected to collide in general. This phenomenon is exhibited via the geometrical construction outlined in this chapter.
