A rigorous Wiener-Hopf approach is used to investigate the band stop filtercharacteristics of a coaxial waveguide with finite-length impedance loading. The representation of the solution to the boundary-valueproblem in terms of Fourier integrals leads to two simultaneous modifiedWiener-Hopf equations whose formal solution is obtained by using thefactorization and decomposition procedures. The solution involves 16infinite sets of unknown coefficients satisfying 16 infinite systems oflinear algebraic equations. These systems are solved numerically and somegraphical results showing the influence of the spacing between the coaxialcylinders, the surface impedances, and the length of the impedance loadingson the reflection coefficient are presented
