Nanometer-scale photon confinement in topology-optimized dielectric cavities
Marcus Albrechtsen, Babak Vosoughi Lahijani, Rasmus Ellebæk Christiansen +8
Nanotechnology enables in principle a precise mapping from design to device but relied so far on human intuition and simple optimizations. In nanophotonics, a central question is h…
Buckling and yield strength estimation of architected materials under arbitrary loads
Morten N. Andersen, Yiqiang Wang, Fengwen Wang +1
Buckling strength estimation of architected materials has mainly been restricted to load cases oriented along symmetry axes. However, realistic load scenarios normally exhibit more…
De-homogenization using Convolutional Neural Networks
Martin O. Elingaard, Niels Aage, J. Andreas Bærentzen +1
This paper presents a deep learning-based de-homogenization method for structural compliance minimization. By using a convolutional neural network to parameterize the mapping from…
Synthesis of Frame Field-Aligned Multi-Laminar Structures
Florian Cyril Stutz, Tim Felle Olsen, Jeroen Peter Groen +4
In the field of topology optimization, the homogenization approach has been revived as an important alternative to the established, density-based methods because it can represent t…
Ultra-coherent nanomechanical resonators based on inverse design
Dennis Høj, Fengwen Wang, Wenjun Gao +3
Engineered micro- and nanomechanical resonators with ultra-low dissipation constitute the ideal systems for applications ranging from high-precision sensing such as magnetic resona…
Revisiting the optimal shape of cooling fins: A one-dimensional analytical study using optimality criteria
Joe Alexandersen, Ole Sigmund
This paper revisits the optimal shape problem of a single cooling fin using a one-dimensional heat conduction equation with convection boundary conditions. Firstly, in contrast to…
Topology Optimization with linearized buckling criteria in 250 lines of Matlab
Federico Ferrari, Ole Sigmund, James K. Guest
We present a 250 line Matlab code for topology optimization for linearized buckling criteria. The code is conceived to handle stiffness, volume and Buckling Load Factors (BLFs) eit…
