The input impedance of a hollow-probe-fed, semi-infinite rectangular waveguide

Image theory is used to determine the input impedance of a coaxial feed in a short-circuited, semi-infinite, rectangular waveguide. The analysis is applicable to hollow antenna probes of variable height and lends itself well to accurate numerical evaluation. The numerical results are compared to results obtained from other methods and show the efficacy of using image theory to determine the waveguide input impedance.<
