Inverse design of plasma metamaterial devices for optical computing
Jesse A. Rodriguez, Ahmed I. Abdalla, Benjamin Wang +3
We apply inverse design methods to produce two-dimensional plasma metamaterial (PMM) devices. Backpropagated finite difference frequency domain (FDFD) simulations are used to desig…
Hyperbolic jigsaws and families of pseudomodular groups II
Beicheng Lou, Ser Peow Tan, Anh Duc Vo
In our previous paper, we introduced a hyperbolic jigsaw construction and constructed infinitely many non-commensurable, non-uniform, non-arithmetic lattices of $\mathrm{PSL}(2, \m…
Compressed imitation learning
Nathan Zhao, Beicheng Lou
In analogy to compressed sensing, which allows sample-efficient signal reconstruction given prior knowledge of its sparsity in frequency domain, we propose to utilize policy simpli…
Inverse design of photonic crystals through automatic differentiation
Momchil Minkov, Ian A. D. Williamson, Lucio C. Andreani +5
Gradient-based inverse design in photonics has already achieved remarkable results in designing small-footprint, high-performance optical devices. The adjoint variable method, whic…
TunaGAN: Interpretable GAN for Smart Editing
Weiquan Mao, Beicheng Lou, Jiyao Yuan
In this paper, we introduce a tunable generative adversary network (TunaGAN) that uses an auxiliary network on top of existing generator networks (Style-GAN) to modify high-resolut…
