Parallel Genetic Algorithm in the Optimization Problem of Filter Parameters Based on Coaxial Waveguide with the System of Slots in a Hollow Inner Conductor

Abstract

An automatic procedure based on the genetic algorithm for the filter parameters optimization of the T-mode of a coaxial waveguide and H₁₁-mode of a circular waveguide is developed. The filter based on a coaxial waveguide with the system of slots in a hollow inner conductor is considered. The dielectric beads may be placed between the slots. The numerical algorithm for the boundary problem solution is based on the operator method and mode-matching method. The calculation time for determination of optimal set of filter parameters is essentially reduced due to using a full parallel algorithm.
