Abstract
A method to treat junctions between bodies of revolution (BOR) and arbitrary surfaces is presented. The method is applicable to formulations employing the method of moments to solve surface integral equations for structures consisting of combined BOR and arbitrary surfaces. Harmonic entire domain basis functions are used on the bodies of revolution and triangular surface patches are used on the arbitrary surfaces. A junction is formed by creating a spatially coincident region between a body of revolution and an arbitrary surface. The geometry of the junction region is determined by the arrangement of the triangular surface patches used to form the junction. It determines the accuracy with which the junction currents are modeled. Numerical results are presented to demonstrate the accuracy of the junction models for both radiation pattern and input impedance predictions.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
