dPV: An End-to-End Differentiable Solar-Cell Simulator
Sean Mann, Eric Fadel, Samuel S. Schoenholz +3
We introduce dPV, an end-to-end differentiable photovoltaic (PV) cell simulator based on the drift-diffusion model and Beer-Lambert law for optical absorption. dPV is programmed in…
Physics-informed neural networks with hard constraints for inverse design
Lu Lu, Raphael Pestourie, Wenjie Yao +3
Inverse design arises in a variety of areas in engineering such as acoustic, mechanics, thermal/electronic transport, electromagnetism, and optics. Topology optimization is a major…
Factorized Machine Learning for Performance Modeling of Massively Parallel Heterogeneous Physical Simulations
Ardavan Oskooi, Christopher Hogan, Alec M. Hammond +2
We demonstrate neural-network runtime prediction for complex, many-parameter, massively parallel, heterogeneous-physics simulations running on cloud-based MPI clusters. Because ind…
On the Computation of Power in Volume Integral Equation Formulations
A. G. Polimeridis, M. T. H. Reid, S. G. Johnson +2
We present simple and stable formulas for computing power (including absorbed/radiated, scattered and extinction power) in current-based volume integral equation formulations. The…
Robust topology optimization of three-dimensional photonic-crystal band-gap structures
Han Men, Karen Y. K. Lee, Robert M. Freund +2
We perform full 3D topology optimization (in which "every voxel" of the unit cell is a degree of freedom) of photonic-crystal structures in order to find optimal omnidirectional ba…
Efficient Computation of Power, Force, and Torque in BEM Scattering Calculations
M. T. Homer Reid, Steven G. Johnson
We present concise, computationally efficient formulas for several quantities of interest -- including absorbed and scattered power, optical force (radiation pressure), and torque…
