In both these cases should be known plasma wavelength, its dependence from the amplitude of the signal exciting the SCW. Calculation of this characteristic of SCW on the basis of different models, especially in nonlinear regime, is not exact. That is why physical experiment is important, which lets to define plasma wavelength in linear and nonlinear regimes. In this connection the task of operative physical modelling of SCW in relativistic electron beams and the study of their characteristics in nonlinear model is of actuality.","PeriodicalId":132112,"journal":{"name":"Proceedings of the IEEE - Russia Conference. 1999 High Power Microwave Electronics: Measurements, Identification, Applications.

As a rule, it is polynomial filters with direct coupled cavity or more seldom with quarter-wave coupled ones. In such filters all zeros are located in a passband, and the poles are on a zero frequency and in infinity. The greater selectivity can be achieved if the frequencies of these poles are given the finite values. Frequently in practice, the monotonous increasing of attenuation in stop-band is not required, and the distribution of poles by Butterworth or Chebyshev is not effective, and filters have superfluous electrical and constructive characteristics. A band-pass section is described.","PeriodicalId":132112,"journal":{"name":"Proceedings of the IEEE - Russia Conference. 1999 High Power Microwave Electronics: Measurements, Identification, Applications.
