Modeling of a Traveling-Wave Tube of the Centimeter Range with Counter Pins Type Slow-Wave Structure

Object of current research in counter pins type slow-wave structure. Slow-wave structure is key subsystem of microwave devices such as traveling-wave tube and backwards-wave oscillators. This research includes basic information about slow-wave structures and microwave devices and also theoretical base required to calculate slow-wave structures characteristics and parameters. The main goal of this research is to determine dependency of considered type slow-wave structures dispersion characteristics from their geometrical parameters. VEGA software package is used in research as a tool for modeling microwave devices and their characteristics calculation. Results of modeling shows that counter pins type slow-wave structure can be effectively applied in centimeter range microwave devices and also reveal dependence of slow-wave structures dispersion characteristics from their geometrical parameters.
