摘要： 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.

摘要： The present disclosure discloses an antenna device, which comprises an array antenna and a power divider. The array antenna comprises a plurality of antenna units, and each of the antenna units comprises a conductive sheet engraved with a groove topology pattern, conductive feeding points and a feeder line. The power divider is adapted to divide a baseband signal into a plurality of weighted signals and then transmit the weighted signals to the antenna units arranged in an array via the conductive feeding points respectively. By arraying the antenna units and using the beam forming method, the directionality of the antenna can be designed as needed through phase superposition between the antenna units; and then, a reflective metal plate is provided on the back side of the antenna so that a back lobe of the antenna is compressed. In this way, the miniaturized antenna array can obtain a high directionality.

The method includes: connecting, by a transmitting end, in which a state machine varies with unit time, to a receiving end, the status of a state machine of the receiving end being synchronized with the status of the state machine of the transmitting end; using, by the transmitting end, a pseudocode signal which varies with unit time, to scramble an original signal and a pilot optical signal, and sending, in the form of a visible light signal, the scrambled signal obtained by scrambling; and receiving, by the receiving end, the visible light signal, identifying the scrambled signal of the current period of time by using a pilot optical signal, and decrypting the original signal according to the scrambled signal. Since a visible light signal which is transmitted between a transmitting end and a receiving end is not an original signal, the security of a photonic Internet of Things is improved.

摘要： The present invention relates to a metamaterial and a metamaterial antenna. The metamaterial is disposed in a propagation direction of the electromagnetic waves emitted from a radiation source. A line connecting the radiation source to a point on a first surface of the metamaterial and a line perpendicular to the metamaterial form an angle θ therebetween, which uniquely corresponds to a curved surface in the metamaterial. Each point on the curved surface to which the angle θ uniquely corresponds has a same refractive index. Refractive indices of the metamaterial decrease gradually as the angle θ increases. The electromagnetic waves propagating through the metamaterial exits in parallel from a second surface of the metamaterial. The refraction, diffraction and reflection at the abrupt transition points can be significantly reduced in the present disclosure and the problems caused by interferences are eased, which further improves performances of the metamaterial and the metamaterial antenna.
