In this paper, exact, closed-form expressions are derived for the electromagnetic fields associated with two-dimensional, traveling-wave current strips radiating into a homogeneous space. The field expressions involve incomplete Lipschitz-Hankel integrals of the Hankel form. Convergent and asymptotic series expansions for the incomplete Lipschitz-Hankel integrals allow the fields to be computed more efficiently than was previously possible using numerical integration. Two-dimensional, traveling-wave current strips are important because they appear in problems involving physical optic scattering from strips, diffraction through slits, and radiation from parallel plate waveguides. The problem of physical optic scattering from a strip is investigated in this paper.
