Course Objective

High frequency solutions to Maxwell equations. Geometrical Optics (GO), the Geometrical Theory of Diffraction (GTD), the Uniform Geometrical Theory of Diffraction (UTD), Equivalent Current Methods (ECM) and their application. Aperture integration, physical optics, method of stationary phase and the Physical Theory of Diffraction (PTD). Curved surface diffraction.

Learning Outcomes of the Course Unit

1   Firstly investigate the possible high frequency solutions obtained from the Maxwell equations.
2   These GO solutions represents the ray tracing propagation.
3   The presentation of the diffraction phenomena (firstly halfplane or wedge canonical shpaes) as in the ray format.
4   Then the contour integration (Equivalent current method) and 2D surface integration (physical optics) type further techniques in the solution of the high frequency scattering problems.
5   Then undersatnding of these ray based or surface integration techniques in the application of the scattering problems.
