Maximizing the quality factor to mode volume ratio for ultra-small photonic crystal cavities
Fengwen Wang, Rasmus Ellebæk Christiansen, Yi Yu +2
Small manufacturing-tolerant photonic crystal cavities are systematically designed using topology optimization to enhance the ratio between quality factor and mode volume, Q/V. For…
Revisiting topology optimization with buckling constraints
Federico Ferrari, Ole Sigmund
We review some features of topology optimization with a lower bound on the critical load factor, as computed by linearized buckling analysis. The change of the optimized design, th…
Simple single-scale microstructures based on optimal rank-3 laminates
Erik Träff, Ole Sigmund, Jeroen Groen
With the goal of identifying optimal elastic single-scale microstructures for multiple loading situations, the paper shows that qualified starting guesses, based on knowledge of op…
A "poor man's" approach to topology optimization of natural convection problems
Janus Asmussen, Joe Alexandersen, Ole Sigmund +1
Topology optimization of natural convection problems is computationally expensive, due to the large number of degrees of freedom (DOFs) in the model and its two-way coupled nature.…
Optimization and projection of coated structures with orthotropic infill material
Jeroen Groen, Jun Wu, Ole Sigmund
The purpose of this work is two-fold. First, we introduce an efficient homogenization-based approach to perform topology optimization of coated structures with orthotropic infill m…
