DiffRayve: Differentiable Ray-Wave Method for Polarized and Unpolarized Diffractive-Refractive Optical Systems
Samuel Audia, Shrey Patel, Dinesh Manocha +1
Current deep optics simulations struggle to balance high fidelity with computational efficiency, particularly for complex polarized and diffractive systems. To address this, we int…
Accelerated, Memory-Efficient Far-Field Scattering Computation with Monte Carlo SBR
Samuel Audia, Dinesh Manocha, Matthias Zwicker
We introduce a Monte Carlo integration-based Shooting and Bouncing Ray (SBR) algorithm for electromagnetic scattering, specifically targeting complex dielectric materials. Unlike t…
How Learnable Grids Recover Fine Detail in Low Dimensions: A Neural Tangent Kernel Analysis of Multigrid Parametric Encodings
Samuel Audia, Soheil Feizi, Matthias Zwicker +1
Neural networks that map between low dimensional spaces are ubiquitous in computer graphics and scientific computing; however, in their naive implementation, they are unable to lea…
VidSole: A Multimodal Dataset for Joint Kinetics Quantification and Disease Detection with Deep Learning
Archit Kambhamettu, Samantha Snyder, Maliheh Fakhar +4
Understanding internal joint loading is critical for diagnosing gait-related diseases such as knee osteoarthritis; however, current methods of measuring joint risk factors are time…
Indoor Wireless Signal Modeling with Smooth Surface Diffraction Effects
Ruichen Wang, Samuel Audia, Dinesh Manocha
We present a novel algorithm that enhances the accuracy of electromagnetic field simulations in indoor environments by incorporating the Uniform Geometrical Theory of Diffraction (…
