Finite-Difference Time-Domain Simulation for Three-dimensional Polarized Light Imaging

, 2016
Three-dimensional Polarized Light Imaging (3D-PLI) is a promising technique to reconstruct the nerve fiber architecture of human post-mortem brains from birefringence measurements of histological brain sections with micrometer resolution.

Finite-Difference Time-Domain Method

, 2014
In this chapter, analysis of sound and vibration using the Finite-Difference Time-Domain method (FDTD method) is illustrated. In Sect. 2.1, the fundamentals of the FDTD method are described. In the FDTD method, several error factors caused by discretization of sound field are pointed out. As methods to solve such problems, in Sect.

Stability and Convergence Analysis of a Domain Decomposition FE/FD Method for Maxwell’s Equations in the Time Domain

Algorithms, 2022
Stability and convergence analyses for the domain decomposition finite element/finite difference (FE/FD) method are presented. The analyses are developed for a semi-discrete finite element scheme for time-dependent Maxwell’s equations.

Efficient ferromagnetic core impedance model with application to finite-difference time-domain simulation

Physical Review Special Topics. Accelerators and Beams, 2012
A frequency-dependent impedance model for laminated ferromagnetic cores is presented and analyzed. The model assumes a multiple-winding ferromagnetic induction core composed of multiple thin layers with linear material response.

Investigation of Plasmonic Properties of a Rhodium Nanoshell Based Optical Nanomaterial

Medžiagotyra, 2022
In noble metals, surface plasmons may be induced by incident light, resulting in good plasmonic properties that can be widely utilized. In this work, an optical nanomaterial based on a spherical nanoshell structure consisting of rhodium and dielectric is

Finite-Difference Time-Domain Study of Guided Modes in Nano-plasmonic Waveguides

, 2007
A conformal dispersive finite-difference time-domain (FDTD) method is developed for the study of one-dimensional (1-D) plasmonic waveguides formed by an array of periodic infinite-long silver cylinders at optical frequencies.

Nondiffractive sonic crystals [PDF]

, 2006
We predict theoretically the nondiffractive propagation of sonic waves in periodic acoustic media (sonic crystals), by expansion into a set of plane waves (Bloch mode expansion), and by finite difference time domain calculations of finite beams.
