Applications of Riemann-Hilbert Problem Techniques to Electromagnetic Coupling Through Apertures

摘要

The Riemann-Hilbert techniques as they are applied to problems of electromagnetic coupling through apertures will be described. This approach will be illustrated with the example of a plane wave incident on a slitted cylinder enclosing a concentric impedance surface. This problem encompasses the coupling to an empty cylinder as well as to a cylinder enclosing a conducting wire or cable. The results for various angles of incidence will be presented for several cases of aperture and cylinder size. Special consideration will be given to the case in which the direction of incidence coincides with an edge of the aperture and the center of the cylinder. Comparisons with moment method results will also be made. (ERA citation 09:024395)
