时间:03-24 整理:3721RD 点击:
My friends I need information about dispersion do you have any special paper about it i ahve the Tafloves book else then that do you have other resources about dispersion especially i need some simultion results of diepersion relations see you soon with best regards

See the links below for info on numerical dispersion in FDTD:
