Calculation and comparison for the axial electric field profile in multi-gap Hughes-type coupled cavity chain

Abstract

Considering the coupling of electric field between the adjacent cavities of multi-gap Hughes-type coupled cavity chain, the axial electric field profile is analytically expressed by hyperbolic secant function and calculated by polynomial curve-fitting program to decrease the calculating error in this abstract. The analytic results are in good agreement with those calculated by CST-MWS code.
