Electromagnetic Penetration Into a Finite Coaxial Cylinder with a Recessed Inner Conductor,

The electromagnetic penetration into a finite coaxial cylinder illuminated by a uniform plane wave of arbitrary incidence is investigated by combining the results of several individual Wiener-Hopf analyses. The circular to coaxial waveguide junction within the cylinder is fully characterized through such a technique. A simple equivalent circuit for this junction and the other elements of the system are combined into an equivalent Norton source and equivalent load admittance which is valid under most practical situations. The power dissipated within the coaxial line section of the system is then easily calculated for any given load, except those in the vicinity of the perfectly matched load. Author
