Genetic Algorithm Optimization of a Traveling Wave Array of Longitudinal Slots in a Rectangular Waveguide

Abstract

Genetic Algorithm is used to optimize the performance characteristics of a traveling wave array consisting of longitudinal slots cut in the broad wall of a rectangular waveguide. An analysis method employing a loaded transmission line to model the slot arrays is employed. External mutual coupling is considered. The self admittance of the radiating slots is computed using the method-of-moments technique applied to the pertinent integral equations. Numerical results indicate typical performance improvements possible using the genetic algorithm optimization.
