Interactions Between Microwaves and Nonlinear Materials: An Optimization Procedure Based on Genetic Algorithms

The interaction between microwaves and nonlinear materials is the topic dealt with in this paper. With reference to nonlinear dielectrics of finite extent (nonlinear scattering) and characterized by Kerr-like nonlinearities, the starting point of the mathematical formulation is an integral equation approach in which (after discretization of the continuous model) an optimization problem is numerically solved by a procedure based on a genetic algorithm. In the paper, the problem formulation in described and some preliminar numerical results are reported.
