MODIFICATION OF THE COUPLED INTEGRAL EQUATIONS METHOD FOR CALCULATION OF THE ACCELERATING STRUCTURE CHARACTERISTICS

In this paper we present modification of coupled integral equations method (CIEM) for calculating the characteristics accelerating structures. earlier developed CIEM schemes are derived unknown electrical fields at interfaces that divide adjacent volumes. addition to standard division structured waveguide by between cells, propose introduce new in places where electric field has simplest transverse structure. Moreover, system is formulated longitudinal contrast approach unknowns. The final vector contain expansion coefficients these additional interfaces. This makes it possible deal with a physical quantity plays an important role acceleration particles (a field), and obtain approximate case slow change parameters.
