Optimal design dielectric layer of Lunberg-lens antenna

The analysis and the computation to the Luneberg lens center even dielectric sheet and the layered medium ball has been carried on in this article. The most superior coefficient of dielectrical loss variable equation has been obtained. At the same time the relation of N and the relative error has been analyzed, and some results have been got, such as the ideal Luneberg lens coefficient of dielectrical loss and the r/R integral and the N relations, and the general Luneberg lens antenna only to need about 10 on a lines.
