A Wiener-Hopf analysis of the coaxial waveguide radiator

In the present work, by formulating the radiation from a semi-infinite coaxial waveguide in a different manner that described in [1], we obtained a single modified Wiener-Hopf equation whose solution involves three sets of infinitely many expansion coefficients satisfying three infinite systems of linear algebraic equations. These systems are then solved numerically and some graphical results showing the effects of the radii of the inner and outer cylinder on the radiation phenomenon are presented.
