    Hybrid TEM wave radiation from a coaxial waveguide with a semi-infinite PEC outer cylinder and an infinite inner cylinder loaded with partial impedance
    (Electromagnetics Academy, 2015) Karayahşi,K.; Tayyar,I.H.; Dolma,A.
    In this work, the radiation of a hybrid TEM mode from a coaxial waveguide with an infinitely thin semi infinite outer cylinder made of perfect electric conductor and an infinite inner cylinder lying along axial direction which has piecewise surface impedance has been analyzed through the Wiener-Hopf technique in conjunction with the mode matching method.

    A Wiener-Hopf analysis of the coaxial waveguide radiator
    (2011) Tayyar,I.H.; Buyukaksoy,A.
    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. © 2011 IEEE.
