A discrete variable based methodology for topology optimization considering spatially uneven manufacturing errors

open access: yesArchives of Electrical Engineering, 2023
: Manufacturing errors (MEs) are unavoidable in product fabrication. The om-nipresence of manufacturing errors (MEs) in product engineering necessitates the development of robust optimization methodologies. In this research, a novel approach based on the

Topology optimization of coupling between slab and photonic crystal waveguide [PDF]

open access: yes, 2008
We employ topology optimization with the finite-element method to improve the coupling between a slab waveguide and a photonic crystal waveguide. Here, we apply topology optimization in a small design region to realize the improvement of the coupling ...
