- Title
Dynamic field behavior near the edge of a dielectric wedge.

- Abstract
A physical optics approximation for the fields scattered by a dielectric wedge is obtained in analytic forms for plane-wave incidence. This is corrected by numerically calculating two extinction integrals by assuming surface currents expanded in Neumann series along two wedge interfaces. Calculated dynamic fields either for TE and TM modes are compared with those of static fields near the edge tip. It is shown that the dynamic fields approach the corresponding static fields for a distance between the field point and the wedge tip less than 10-2λ, where λ is the free-space wavelength. The dynamic field behavior for this distance larger than 10-2λ up to 3λ shows a smooth transition to the far-field behavior, i.e., the ratio of Eρ versus Hz becomes almost a constant. © 2000 John Wiley & Sons, Inc.
