HI all, I did wrote codes for 2D FDTD TFSF TMZ mode using yee algorithm. But the output I got was not as expected. The curve was bended, and major leaking after some time when approaching ilast, jlast. Can anyone help me to analyze the output graph eg, why the leaking happened, and why the curve was bending. I didn't put any ABC,PEC or PML for this time being, and 100% referred to taflove. t = 68sec t=79sec t=94sec t=104sec please advice and thank you in advanced.
