Scattering of an E-polarized plane wave by a dielectric filled slotted cylinder

This paper studies scattering by a dielectric filled, slotted metal cylinder. The incident field is a plane wave with E-vector parallel to the axis of the cylinder. The problem is solved using a convergent low frequency solution as well as by the method of moments, and the two solutions are found to be in good agreement. They also agree quite well with experiment. Explicit expressions for the scattered far field are obtained in the low frequency limit, and many curves are presented in the range 1 ≤ 2 π × radius/wavelength ≤ 10.
