Analysis of gaussian beam diffraction by a conductive half-plane

Beam diffraction by a conductive half plane is a problem in electromagnetics that arises when a beam of electromagnetic radiation encounters a conductive surface. The surface diffracts the beam, and the resulting field distribution can be complex. The problem of beam diffraction by a conductive half-plane has a long history, dating back to the work of Sommerfeld in the early 20th. Sommerfeld developed a rigorous solution to the problem, which is still used today. In recent years, there has been renewed interest in the problem of beam diffraction by a conductive half plane due to its applications in a number of fields, including antenna design, radar systems, and optical systems. This thesis studies the scattering and diffraction of a Gaussian beam by a conductive half-plane. To generate a Gaussian beam complex point source method is used. To evaluate geometrical optics and diffracted fields, the far-field approximation is used. Obtained diffracted and scattered fields plotted and examined numerically with the help of MATLAB.
