Abstract
This paper presents a study on surface wave contribution on a material coated with a discontinuity. The spectral integral is heuristically constructed from Weiner-Hopf (W-H) solution based on impedance surface. The heuristic spectral is also modified so that the spectral can be treated the material coated with some thickness. This leads one to obtain the exact surface wave pole from exact Fresnel reflection coefficient. The surface wave contribution is rigorously extracted from modified heuristic spectral integral by using residue theorem. It is found that this surface wave is excited from diffracted field at the discontinuity. This work shows that how can we rigorously obtain the surface wave contribution from the modified heuristic solution. This will enlighten one to be able to understand the surface wave behaviors on any material coated with discontinuity.
