Creation of orotrons with a double-row periodic structure for the short-wavelength part of the millimeter range and for the submillimeter range

A terahertz orotron with double-row periodic structure and broad electron beam

“…Orotrons with DPS have been extensively studied at the Kotel'nikov Institute of Radio Engineering and Electronics since their invention (see, e.g., [4]). Pres ently these investigations are aimed at using the advan tages of these devices in the terahertz frequency range [5].Previously, it was theoretically predicted [6] that, in orotrons with DPS and a hemispherical OR for the centimeter wavelength range, the width (2C) of the planar electron beam can be increased up to at least two caustic radii (r c ) without decreasing efficiency of the electron-wave interaction. This possibility is related to the fact that the RF field amplitude distribu tion for the main mode (TEM 00q ) is Gaussian both along and across the electron beam.…”
