Abstract

In this paper we present an analytical method, employable with commercial full-wave electromagnetic CADs, which allows full-wave simulations of electromagnetically (EM) large structures, in terms of wavelength, such as linear accelerator cavities (LINACs) and a very accurate estimation of their operating frequency. The proposed technique is based on the exploitation of rotational symmetry through the definition of equivalent axially-symmetric volumes which replaces the non axially-symmetric ones inside the structure being analyzed. After a theoretical study, we show the successful application of the method in the real case study of a Drift Tube Linac (DTL) cell.
