Evaluation of the uniform theory of diffraction for edge diffraction at low frequency

Shukayr, Riman2001

This thesis examines the UTD diffraction coefficient's limitations in accuracy for a half plane and a wedge at low frequency. The UTD solutions are developed for scattering by a strip and a square cylinder with diffraction considered as a local phenomenon. Single and multiple diffractions are …
