Investigation of “serpentine”-type slow-wave structures in the terahertz range
P. 1–2.
In this paper, dispersion characteristics of "serpentine”-type slow-wave structures, which are promising for the terahertz range use, are calculated. For 3D-modeling, HFSS was used. Program described in work was used in the calculation. Using the obtained characteristics, octopole chain model of the slow-wave structure is constructed. Discrete approach is advisable in solving these problems. Justification of the applied mathematical model for the discrete interaction follows from the difference form of electrodynamic theory of excitation [3]. Requirements to coefficients of the resulting finite-difference equation are high, because their accuracy determines how close the mathematical model of the discrete interaction to the physical laws is. These coefficients have a certain electrodynamic sense and are obtained through the octopole transmission matrix coefficients. In turn, this octopole is a mathematical model of the resonator slow-wave structure cell.

In this paper, the slow-wave structure (SWS) of the “folded waveguide” -type was considered. This SWS is widely used for designing the devices in higher frequencies like millimeter and sub millimeter ranges due to its compactness, increased interaction length, reduced transit time effects, lower voltage requirements, and wide bandwidth. The calculation of its electrodynamic characteristics, ...
