recently i am confused with a problem in FDTD about excitation.Take dipole antenna as an example.Generally the feed gap only one cell.When I decrease the grid length to half of origin, then feed gap have more than one cell(note:feed gap has a fixed area).Unfortunally the impedance results vary...
dipole impedance fdtd
I have 2 problems in FDTD to get help.First thank you for your reading.
1. Zin(w)=V(w)/I(w), how to locate the contour of H for I(t)? Take a dipole as an example. The contour should be around the feed gap or around the arm?
2. When we calculate a strip dipole...
Re: question about CST MWS mesh grid and source,please help
Thanks a lot ,shameemkabir.What you said is very important and useful to me .
Today I test again and found that the results will be incorrect if the frequency range is too large.

meshgrid explained
first,a problem about mesh grid density control.I am really confused with 'lines per wavelength','lower mesh limit' and 'mesh line ratio limit'. What is the relation between them and how to set up these values correct?
second,Is there any special limit on the frequency...
hi,guys.Im confused recently with this topic.Someone had some simple words about this as follows.But im still in obtacle.
t=linspace(-5,5,40); %matlab based model
[x,y]=meshgird(t,t);
z=peaks(x,y);
surf(x,y,z)
hfss_surf_exe();%the interface function
%then the model is built in HFSS.
I havent...
hfss matlab
im doing something in antenna design using GA for optimization.Anyone works this before?thank you for reading and giving me some helps!
