    Abstract: Proposed are triboelectric generator using a lubricant-infused surface controlled by a magnetic field and a manufacturing method thereof. The triboelectric generator 10 includes a substrate 100, an electrode unit 200 positioned on the substrate 100 and including a first electrode 210 and a second electrode 220, a stabilization layer 300 positioned on the substrate 100 and the electrode unit 200 and including a first elastic polymer 310, and a magneto-controllable unit 400 positioned on the stabilization layer 300 and including a lubricant 420 and a plurality of protrusion-shaped microcomposites 410, in which the microcomposite includes a magnetic material 411 and a second elastic polymer 412. The protrusion-shaped microcomposite is partially immersed in the lubricant, improves power generation efficiency, and can perform reversible switching according to the direction of the magnetic field.

    Abstract: A beamforming device in a wireless communication system is provided that includes a phased array antenna, at least one wireless communication circuit, and a lens, wherein the lens comprises a first surface oriented in a first direction, which is the direction toward the phased array antenna, and a second surface oriented in a second direction, which is the opposite direction of the first direction, and a first beam radiated from the phased array antenna is refracted after passing through a first point on the first surface, and forms a first path inside the lens and forms a second path along which the first beam is refracted at a second point on the second surface after passing through the inside of the lens along the first path, wherein the refraction angle at the second point may be formed so as to be dependent on the radiation angle of the first beam.
