Abstract: 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 of the metamaterial of the present disclosure.

Abstract: The present invention relates to a man-made composite material and a man-made composite material antenna. The man-made composite material is disposed in a propagation direction of a plane electromagnetic wave and convert it into a spherical wave. Reverse extensions of the spherical wave intersect at a virtual focus. A line connecting the virtual focus to a point on the second surface of the man-made composite material and a line perpendicular to the man-made composite material form an angle θ therebetween, which uniquely corresponds to a curved surface in the man-made composite material. A set formed by points having the same angle θ forms a boundary of the curved surface to which the angle θ uniquely corresponds. Each point on the curved surface to which the angle θ uniquely corresponds has a same refractive index. Refractive indices of the man-made composite material increase gradually as the angle θ increases.

Abstract: A front feed satellite television antenna includes a metamaterial panel. The metamaterial panel includes a core layer and a reflective panel. The core layer includes a core layer lamella which further includes a circular area and multiple annular areas distributed around the circular area. Within the circular area and the annular areas, refractive indexes are identical at a same radius, and within the respective areas, the refractive indexes decrease gradually as radius increases. The minimum refractive index of the circular area is less than the maximum the refractive index of the annular area adjacent thereto. For two adjacent annular areas, the minimum refractive index of the annular area at the inner side is less than the maximum refractive indexes of the annular area at the outer side. The metamaterial panel can replace conventional parabolic antenna, thus facilitating manufacturing and processing, and further reducing costs.
