About nonlinear theory of two-cavity klystron with a drift space in the form of medium with complex permittivity

The purpose of this work is to construct an approximate nonlinear theory of a klystron amplifier in which a medium with complex conductivity or with metamaterials with negative permittivity is located between the input and output cavities instead of the drift space. Within the framework of the constructed theory, calculate the output characteristics (gain, output power and efficiency) of the described device and compare the results with the classic two-cavity klystron.
