Optimization of Dual-Band Meander-line Polarizer Plates Using a Hybrid Evolutionary Programming Algorithm.

We have applied an evolutionary programming (EP) algorithm with a hybrid mutation operator for optimization of dual-band linear polarization (LP) to circular polarization (CP) and LP (V to H) rotation meander-line polarizer plates. This EP algorithm, which was previously introduced in Hoorfar et al. (2000) for antenna problems, uses a combination of the Cauchy and Gaussian mutation operators in order to exploit the desirable properties of these two operators. The implementation uses a self-adaptive scheme for updating the standard deviation and the scale parameter of Gaussian and Cauchy distributions, respectively, resulting in faster convergence than EP with a Gaussian or EP with a Cauchy mutation.
