Radiation of a charged particle bunch moving along a deeply corrugated structure with a relatively small period

Radiation of a charged particle bunch passing through a deeply corrugated structure with a relatively small period

“…This part of the spectrum is not yet well-understood and takes an increasing interest in the scientific community. One can note only few relevant studies concerning the analysis of the "longwave" range (see, for example, [3][4][5][6][7][8][9][10][11]).…”

“…In short, this method allows replacing a corrugated structure with some anisotropic surface which is characterized by a certain matrix impedance. Recently, we have solved a series of the "longwave" problems where the EBC method was applied [8][9][10][11]. Papers [8][9][10] are devoted to studying the case of shallow corrugated structures, i.e.…”

“…In particular, we showed that, under certain conditions, the configuration of the surface wave can be used for the determination of the bunch size. In contrast to [8][9][10], paper [11] focuses on studying the case of deep corrugation when the structure depth is much greater than its period (more precisely, it is assumed that the depth is of the same order as an inverse wavenumber). In [11], we investigated a situation when a bunch moves along a deeply corrugated planar structure.…”

“…In contrast to [8][9][10], paper [11] focuses on studying the case of deep corrugation when the structure depth is much greater than its period (more precisely, it is assumed that the depth is of the same order as an inverse wavenumber). In [11], we investigated a situation when a bunch moves along a deeply corrugated planar structure. It was shown that the bunch generates surface radiation, and the configuration of the surface wave is rather more complicated than in [9,10].…”

“…In the present paper, the structure under consideration is the same as in [11], i.e. it is the deeply corrugated planar surface.…”
