Retarding System of the Diafraged Rectangular Waveguide Type

摘要： In this paper, we propose fast and sufficiently accurate models for retarding systems (RS) such as double-shifted combs in a rectangular screen and RS of the looping waveguide type based on the diaphragm conductivity calculation in a rectangular waveguide (RW). The conductivity of the capacitive diaphragm in the RW is obtained for electric and magnetic wide walls. Multimode models based on functionals of electric and magnetic types are also proposed. The models facilitate correct account of losses. The dispersion of a double comb and looping waveguide with infinitely thin walls is calculated.
