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…
Designing Photonic Topological Insulators with Quantum-Spin-Hall Edge States using Topology Optimization
Rasmus E. Christiansen, Fengwen Wang, Ole Sigmund +1
Designing photonic topological insulators is highly non-trivial because it requires inversion of band symmetries around the band gap, which was so far done using intuition combined…
Topological Insulators by Topology Optimization
Rasmus E. Christiansen, Fengwen Wang, Ole Sigmund
An acoustic topological insulator (TI) is synthesized using topology optimization, a free material inverse design method. The TI appears spontaneously from the optimization process…
