Title: Novel method for determining the elctromagnetic dispersion relation of periodic slow wave structures
Author: Carmel, Y.; Guo, H.; Lou, R.; Abe, D.; Granatstein, V.; Destler, William
Abstract: A novel method for calculating the dispersion relation of electromagnetic modes in an arbitrary periodic slow wave structure is reported. In this method it is sufficient to know the frequencies corresponding to three special wave number values, with other points calculated using an approximate analytical expression. This technique was successfully applied to determine the dispersion relation of the TM01 mode in a sinusoidally corrugated slow wave structure. This structure is commonly used in relativistic high-power backward wave oscillators and traveling-wave tubes, and is expected to have many additional applications.
