About possible theoretical approach in the linear theory of dielectric twt and devices containing metamaterials

In this paper we present overview of devices using a dielectric as a slow-wave structure. There are increased focus on consideration of dielectric Cherenkov maser (DCM) and resistive-wall amplifier (RWA). This type of devices may be advance in THz range. The principle of the DCM operation is described by two-dimensional planar model with the indication of main advantages of this device. In particular, there are sufficiently large gain and possibility of great tunability range (by varying the beam voltage).
