Opposition effect experimentation and a theoretical investigation involving cylinders

Three theoretical problems are investigated. Two of these address the scattering of plane electromagnetic waves by single infinite circular cylinders. In the first, the cylinder is embedded in a homogeneous half-space. In the second, the cylinder is adjacent to a homogeneous halfspace. The third addresses the scattering produced by three identical, non-coplanar, dielectric cylinders. A backscattered peak, comparable to that of the opposition effect, is obtained for cylinders with diameters comparable to the wavelength of the incident radiation.
