Students will apply the tools to analyze a number of common devices and configurations like waveguides, thin film optical filters, This repository contains MATLAB code for performing 1D and 2D Finite-Difference Time-Domain (FDTD) simulations. There are two sources that interfere to produce fringe pattern. FDTD is Finite Difference Time Domain method,but due to truncated it it will cause the reflectional on its boundary that will cause unnecessary noise to our simulation domain. So 完美匹配层(PML)作为一种有效的吸收边界条件,能够有效抑制边界反射,为开放区域电磁问题的数值模拟提供了精确且稳定的解决方案。 本文将深入探讨PML的基本原理 I'm have developed a 3D FDTD model with a second order ABC in matlab.
