Electromagnetic oscillations in periodic mediums outside the passbands

It was usually assumed that the resonator based on a waveguide has the eigen oscillations that are formed by interference of two waves which propagate in different directions and have equal amplitudes. These patterns are usually called standing waves. We have shown that the eigen oscillations of a resonator which is filled by a layered dielectric can be base on the evanescent (non-propagating) waves. In some cases we need only one eigen wave to compose the eigen oscillation of a closed cavity.

Evanescent oscillations in accelerating structures

Results of our investigations of the properties of the electromagnetic oscillations in the resonators based on the periodic waveguides are represented. These results point out on the possibility of existing in resonant cavities the new type of eigen oscillations based on the evanescent waves. Such oscillations do not exist in the smooth waveguides. They have a longitudinal distribution of electromagnetic field with decreasing (increasing) dependence on the coordinate. We discuss the using of such oscillations for bunching and accelerating of electron beams.
