    Genetic Algorithm Approach To Estimate Radar Cross Section of Dielectric Objects
    (Ieice-inst Electronics information Communications Eng, 2003) Aydin, E; Nakiboglu, KC; Department of Electrical & Electronics Engineering; Department of Electrical & Electronics Engineering; 15. Graduate School of Natural and Applied Sciences; 01. Atılım University
    Genetic algorithm (GA) is a widely used numerical technique to simplify some analytical solutions in electromagnetic theory. Genetic algorithms can be combined with the geometric optics method to tackle electromagnetic scattering problems. This paper presents an extrapolation procedure, which derived, as a first step, a functional representation of the radar cross section (RCS) of three different dielectric objects that was computed via the Mie solution or the method of moments (MOM). An algorithm was employed to fit the scattering characteristics of dielectric objects at high frequencies.

    Optimizing the Performance of Single-Mode Laser Diode System Using Genetic Algorithm
    (Elsevier Sci Ltd, 2004) Aydin, E; Aydın, Elif; Yildirim, R; Aydın, Elif; Department of Electrical & Electronics Engineering; Department of Electrical & Electronics Engineering; 15. Graduate School of Natural and Applied Sciences; 01. Atılım University
    In this correspondence, micro-genetic algorithm (MGA) application results for optimizing the performance of electronic feedback of a laser diode are presented. The goal of optimization is to find the maximum bandwidth of the laser diode with electronic feedback used in fiber optic digital communication. A numerical analysis of the system theory of the single-mode laser diode to obtain numerical results of the gain, the Pulse response, and the harmonic distortion for electronic feedback is also presented. The dependence of the system gain on the feedback gain and delay is examined. The Pulse response is studied and it is shown that a transmission rate over 1 Gbyte/s can be achieved.
