How can we implement TF-SF in a two dimensional Maxwell-Helmholtz equation in FDTD method?

01 January 1970 0 2K Report

Hi, I have written a code for solving the Helmholtz-Maxwell electromagnetic equation using finite difference time domain (FDTD) method. There is not much material available online for this equation. All the algorithms available online or offline are based on Yee's leap frog method.

I have followed the book Computational electrodynamics by Taflov and a PDF by Prof. John S that is available online. Now when I follow Yee's grid then TFSF work very well but when I try to implement it on my code then it doesn't work at all. I'm following the same method to suppress the leftward traveling wave as discussed in these sources albeit with slight modification.

If someone has done it before and can help me on this then it would be of great help.

What is your perception on using visual analysis or quantitative approaches to evaluate data from single-case research designs (n of 1 trials)?

Results of single-case research designs (i.e., n-of-1 trials) are often evaluated by visually inspecting the time-series graph and computing quantitative indices. A question our research team is...
