A method of moments analysis of a hollow, tubular cylinder which perpendicularly penetrates an air‐dielectric interface is carried out using a potentiallike formulation. Currents are excited on this cylinder by means of an azimuthally symmetric source. Since the thin‐wire kernel is not used and real‐axis integration of Sommerfeld integrands is employed, this analysis provides an independent check on the numerical electromagnetics code for the case of thin wires which perpendicularly penetrate an air‐dielectric interface. Sample results are given for thin wires which penetrate an air‐water interface.
