High-frequency scattering by a conic frustum
Abstract
Both space and surface rays are required for a complete description of the scattering field in the case where the diffracting body has both smoothly curved surfaces and sharp edges. The radiation from a monopole mounted on a conic frustum was calculated using the Keller's (1962) geometrical theory of diffraction. An experimental verification of hybrid diffraction coefficients for surface waves was carried out. Consideration is given to a shadow region where surface waves play an important role. A good agreement between theoretical and experimental data was found, except in penumbra regions and regions where the theory was inapplicable.
