A hemispherical Luneberg dielectric lens including a hemispherical center layer having a hemispherical outer surface, and a plurality of hemispherical dome-shaped layers each having concentric hemispherical inner and outer surfaces, the outer surfaces of the center layer and dome-shaped layers having different diameters and the inner surfaces of said dome-shaped layers having different diameters. The soft coil mesh is formed by an elongated microcoil element that forms the helical elements of a macrocoil element. Entity references for corresponding entities of the data system are constructed based on a comparison of the retrieved entity records and the extracted attribute values. Then, the decoder decodes normal packet data selected from the first packet data and the second packet data, and outputs the decoded data to a video switch.
