摘要： The present disclosure relates to a metamaterial for diverging an electromagnetic wave, which comprises at least one metamaterial sheet layer. Refractive indices of the metamaterial sheet layer are distributed in a circular form with a center of the metamaterial sheet layer, and the refractive indices remain unchanged at a same radius and increase gradually with the radius. The present disclosure changes electromagnetic parameters at each point of the metamaterial through punching or by attaching man-made microstructures so that the electromagnetic wave can be diverged after passing through the metamaterial. The metamaterial of the present disclosure features a simple manufacturing process and a low cost, and is easy to be implemented. Moreover, the metamaterial of the present disclosure has small dimensions and does not occupy a large space, so it is easy to miniaturize apparatuses made ofthe metamaterial of the present disclosure.

摘要： The present invention discloses a Cassegrain satellite television antenna comprising a metamaterial plate. The metamaterial plate comprises a core layer. The core layer comprises core sublayers. Each core sublayer comprises a circular area and a plurality of annuli distributed around the circular area. The refractive indexes of points at the same radius in the circular area and annuli are the same. In their respective areas the refractive indexes of the points in the circular area and the annuli gradually decrease with the increase of the radius. The minimum value of the refractive index in the circular area is smaller than the maximum value of the refractive index in the adjacent annulus. In two adjacent annuli, the minimum value of the refractive index in the inner annulus is smaller than the maximum value of the refractive index in the outer annulus. According to the Cassegrain satellite television antenna of the present invention, the traditional parabolic antenna is replaced with a sheet-like metamaterial plate which is easier to process and has a lower cost. In addition, the present invention also provides a satellite television receiving system equipped with the above-mentioned Cassegrain satellite television antenna.
