COUPLING IMPEDANCES OF MUFFIN-TIN STRUCTURES WITH CLOSED AND OPEN SIDES

摘要

In a previous work the eigenmodes of a muffin-tin structure limited with lateral electric walls were calculated using the mode matching technique. Now a modulated off axis beam is introduced and the beam induced fields, as well as the longitudinal coupling impedances are calculated. Furthermore, in order to get the fields in case of the open structure, the discrete set of modes in the field expansions was replaced by a continuous spectrum. The appearing Fourier integrals are determined by means of the residuum calculus.
