Abstract

An exact series representation was derived for integrals whose integrands are products of cosine and spherical wave functions. For purposes of illustration, the kernel integral for a cylindrical dipole and the vector potential for a uniform current circular loop were evaluated. Further, the representation was used to develop a new and useful series expansion for a spherical wave in terms of cylindrical harmonics. A general closed-form far-field approximation was also established and shown to reduce to the known results for the special cases of the cylindrical wire kernel and the uniform current loop vector potential.
