Hi, I used
[new_E_ftfxfy_o,new_E_ftfxfy_e,New_tWindow,New_xWindow,New_yWindow]= ...
changeWindowSize(obj,E_ftfxfy_o,E_ftfxfy_e,...
'xWindow',0.002,'yWindow',0.002,'tWindow',2e-12,'Nx',1024,'Ny',64,'Nt',1024);
to reduce x&yWindow size from 0.01m to 0.002m while increase tWindow size from 5e-15s to 2e-12s.
The result for the ordinary pol. is correct.

After (Itx)

While in the extraordinary pol.
