Unifying and accelerating level-set and density-based topology optimization by subpixel-smoothed projection
Alec M. Hammond, Ardavan Oskooi, Ian M. Hammond +3
We introduce a new "subpixel-smoothed projection" (SSP) formulation for differentiable binarization in topology optimization (TopOpt) as a drop-in replacement for previous projecti…

Inverse design of 3D-printable metalenses with complementary dispersion for terahertz imaging
Mo Chen, Ka Fai Chan, Alec M. Hammond +2
This study formulates a volumetric inverse-design methodology to generate a pair of complementary focusing metalenses for terahertz imaging: the two lenses exhibit equal and opposi…
