I am studying FDTD now.But I have some problems about it.For instance,the explanations of YEE grids in books.It says through alternational iterations of electric field and magnetic field in time axis,we can get electromagnetic results.However, I do not understand how to get initial values of electromagnetic which is used in alternational iterations.Please give me some hints or assists,Thanks!!!!!
Hi!
The initial values of em field is set to zero excpet at the source region(where the values are determined by the excitation).
And then, the alternational iterations begin.
Thank you Fuga!
Now I have another problem.I have tested a 1D example in matlab.However,I found that Gaussian Pulse distorted when EM transmitting. Especially, Gaussian Pulse width is narrow,relatively.Which error causes this phenomena?numerical calculation, narrow width of Gaussian Pulse or some others?Thanks!!!
