Abstract

Topology optimization is a state-of-the-art tool for detecting the best material layout in a physical space to obtain certain goals. Initially developed as a structural engineering tool, it has been recently used in electromagnetics and has shown immense potential. The aim of this work is to build a framework for applying the topology optimization method in electromagnetics using a modified binary particle swarm optimization (BPSO) algorithm. In this thesis, a very classic problem of coax to waveguide transition has been considered, and a novel solution has been given using topology optimization. The steps to implementing topology optimization using BPSO have been thoroughly documented. The optimized transition has been fabricated and tested to give a 50% improvement over the initial guess. The optimized transition has been shown to outperform the traditional solutions suggesting the potential of this technique in creating elegant solutions to complex electromagnetic problems.
