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

Topology optimisation: increasing the speed and reliability of design [PDF]
In this paper, topology optimisation is applied to the design of the rear fuselage of an unmanned aerial vehicle (UAV). A comparison is drawn between the performance of a design created through evolutionary structural optimisation (ESO) and a baseline ...
