Electromagnetic Characterization of Symmetric and Asymmetric Modes in a Disk-Loaded Structure

The electromagnetic (EM) characteristics of symmetric and asymmetric modes in a disk-loaded structure have been investigated. The study focused on those EM characteristics that affect the dynamics of electrons in amplifier. Two different frequency bands have been considered, X-band and Ka-band, referring to two main activities at Stanford Linear Accelerator Center and Cornell University. The impact of the geometry on the EM characteristics is presented and some simple analytic relations have been developed based on simulations.
