This problem had bean solved via modal expansion technique. However, in case where the scatterer size is extremely large compared with incident wavelength, the previously obtained solutions are no long practical. In this paper, a practical treatment is developed. The Gaussian beam is expanded in terms of continuous plane waves with amplitudes and phases given by a Gaussian weighting functions. The continuous plane wave spectrum of the Gaussian beam is obtained. Since the scatterer size is very large compared with the incident wavelength, the scattering of each plane wave by the conducting circular cylinder is computed via geometrical optics technique. Thus, the evaluation of the Gaussian beam scattering from the conducting circular cylinder reduces to evaluating the inverse Fourier transform to the scattered plane waves. Numerical results using a code developed under MATLAB environment is obtained. The obtained solution is compared with the previously published solutions that are based on modal expansion technique and good agreement is achieved.","PeriodicalId":282391,"journal":{"name":"Second Workshop on Teaching Photonics at Egyptian Engineering Faculties and Institutes (Cat.

The design of the network depends heavily on the technology underlying these components, opto-electronics for NAS and photonics for ONN. These areas show large and fast development which will have an impact on network design. A series of characterization experiments were set up and conducted for characterization of the optical fiber and the laser diodes used. Among the important components in this project was a self study item of the student choice for one of the components of the link or the different aspects of the WDM systems and networks. The main features of the component with up to date information were required. The items ranged from fiber fabrication to soliton propagation in fibers and from WDM network layers to topologies as well as DFB and quantum well lasers.","PeriodicalId":282391,"journal":{"name":"Second Workshop on Teaching Photonics at Egyptian Engineering Faculties and Institutes (Cat.
