FDTDX is an efficient open-source Python package for the simulation and design of three-dimensional photonic nanostructures using the Finite-Difference Time-Domain (FDTD) method. Built on JAX, it ...

Abstract: Modeling and simulation strategies for radar cross section (RCS) prediction are reviewed, and a novel FDTD-based virtual RCS prediction tool is introduced in this two-part paper. Part 1 is ...

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 ...

Time-domain simulation of woodwind instruments typically involves the development of separate discrete-time sub-models for the excitation mechanism and the resonator. These components have largely ...

Short implementation of acoustic wave propagation using finite-differences in time domain and CUDA. The code is solving second order wave equation in pressure formulation, O(2,8). Computational domain ...

We discuss the application of the forward-mode differentiation method to Maxwell’s equations, which is useful for the sensitivity analysis of photonic devices. This approach yields exact gradients and ...

Electron energy-loss spectroscopy (EELS) is a unique tool that is extensively used to investigate the plasmonic response of metallic nanostructures. We present here a novel approach for EELS ...
