摘要： A frequency selective reflector reflecting electromagnetic waves in a particular frequency band to a direction different from a regular reflection direction, the frequency selective reflector comprising: a reflecting member reflecting the electromagnetic waves; and a dielectric layer that: is disposed at an incident side of the electromagnetic waves with respect to the reflecting member; includes a concave and convex structure in which a plurality of a unit structure including a thickness distribution of increasing thickness in a predetermined direction is arranged; and transmits the electromagnetic waves, wherein the unit structure of the dielectric layer includes a plurality of cell regions of which thickness differs from one another; the dielectric layer includes, as the unit structure, at least a first unit structure including three or more of the cell regions of which thickness differs from one another; and a reflection direction of the electromagnetic waves is controlled by controlling a relative reflection phase distribution of the electromagnetic waves by the thickness distribution of the dielectric layer.

摘要： Provided are a structure and a building material that are capable of reflecting radio waves over a wide range of space. Provided is a structure comprising a radio wave reflector including a radio wave reflecting material for reflecting radio waves, wherein when the radio wave reflector is caused to reflect a radio wave at an incident angle of an incident wave of 15 degrees or more and 75 degrees or less at a frequency of the incident wave of 3 GHz or more and 5 GHz or less, 25 GHz or more and 30 GHz or less, or 150 GHz or more and 300 GHz or less, the intensity of a reflective wave as specular reflection of the incident wave is -30 dB or more relative to the incident wave, and in a virtual plane including an incident direction of the incident wave and a reflection direction of the reflective wave, when reception angular positions of the reflective wave are varied within an angle range of -15 degrees or more and +15 degrees or less with respect to the specular reflection direction, kurtosis of distribution of intensity of the reflective wave at each of the reception angular positions is - 0.4 or less at least at one frequency.

摘要： Embodiments of this application provide a dual reflector antenna, a dual reflector antenna control method, and a communication system, and relate to the field of antenna technologies. The dual reflector antenna includes a primary reflector, a secondary reflector, a feed, a first driving structure, and a connecting piece. The secondary reflector is opposite to the primary reflector, and the feed is configured to radiate an electromagnetic wave to the secondary reflector. The first driving structure has a telescopic shaft. The connecting piece is connected to the secondary reflector. When the telescopic shaft is extended, the telescopic shaft abuts against the connecting piece, to drive the secondary reflector to restore to an initial position, where the initial position is a position in which a plane on which a diameter of the secondary reflector is located is parallel to a plane on which a diameter of the primary reflector is located.

摘要： A radar system is proposed. The radar system comprises a radar sensor comprising a first antenna configured to emit a radar beam towards a predefined region. The radar system comprises a reflector spaced apart from the radar sensor and configured to redirect at least part of the radar beam towards a target region different from the predefined region. The radar sensor comprises a second antenna configured to receive a reflection of the radar beam originating from the target region.
