Grid Specification

By Emerson Melo, Tom Chen and Xin Lei

In this tutorial, you will learn how to set up the FDTD grid to obtain accurate simulation results. We will demonstrate the differences between uniform and non-uniform grids, and how to utilize them to optimize the simulation mesh. Additionally, you will learn how to calculate the symmetric and anti-symmetric modes of a directional coupler.
