Über eine anschauliche Darstellung der Vorgänge bei der Fortpflanzung von unstetigen Signalen in Wellenleitern

Summary The electromagnetic radiation in a wave guide due to an electric dipol may be considered as consisting of the incident primary radiation and the waves generated by successive reflections from the walls of the pipe. This picture was applied to study the propagation of a cut-off periodic wave, first generally for any section of the wave guide and then more in detail for a rectangular section. The field consists in any given moment after the beginning of the dipol radiation of a finite number of such waves, the fronts of which are generally electromagnetic wave surfaces. In the foremost wave front and the points just behind it the electromagnetic field is given by the primary radiation. But very soon the field subsides in the forerunner till the arrival of the first main wave.     

Influence of the cross-phase modulation effect on the polarization states of waves transmitted through a non-linear Fabry–Pe´rot cavity

An analysis of the influence of the cross-phase modulation effect on the polarization states of waves transmitted through a non-linear Fabry–Pe′rot resonator with a self- focusing and self-defocusing Kerr medium is presented. The case is considered of two plane waves with different wavelengths incident on a non-linear Fabry–Pe′rot cavity. It is shown that the polarization states of the transmitted waves change bistably or multistably and depend on the parameters of incident waves and the resonator. This revised version was published online in November 2006 with corrections to the Cover Date.
