Abstract: Staircase approximation in the simulation of the arbitrarily irregular surface will cause artificial interference of wavefield. The body-fit coordinate transformation can accurately simulate ...
Abstract: We present a comprehensive tutorial on the finite-difference time-domain (FDTD) modeling of space, time, and space-time-varying media, building upon our previous review by offering a ...
The Finite-Difference Time-Domain method is a numerical technique for solving Maxwell's equations directly in the time domain. Instead of approximating solutions analytically, FDTD discretizes space ...
This repository contains the official reference implementation of FDFO, a method for fine-tuning flow-based diffusion models using finite difference gradient estimation. We fine-tune Stable Diffusion ...
