An analysis is presented of the scattering of a plane electromagnetic wave at oblique incidence from a circular dielectric cylinder. Under certain conditions this scattering process involves the excitation of cyclic surface Sommerfeld waves (SWs) capable of traveling large distances along the cylinder. It is shown that the interaction of SWs of low azimuthal order with the cylinder’s continuous (radiation) modes gives rise cyclic Sommerfeld resonances (SRs) analogous to the well-known Wood’s anomalies in the plane wave scattering from one-dimensional metallic diffraction gratings. Conditions necessary for the effective excitation of SWs and SRs are established and how SWs and SRs contribute to mode formation in microstructured optical fibers is discussed.
