This chapter utilizes the parabolic equation method to analyze the diffraction from a thin cylindrical conductor (dipole) and a strip. The possibility of solving this problem was previously mentioned. The theory of dipoles is widely examined in the professional literature. The general physical properties of current waves on dipoles were studied in previous works. This chapter shows that the results obtained in previous works can be derived more simply by using the parabolic equation. In addition, these results include near field calculations, and in the limit as a → ∞ (a is the radius of the dipole), also describe the current waves on a strip.
