Title:
BEAMFORMER
Document Type and Number:
WIPO Patent Application WO/2023/073810
Kind Code:
A1
Abstract:
A beamformer (10) of this invention is a beamformer configured to perform beamforming of an input electromagnetic wave and output an output electromagnetic wave, which includes a cell made of a metamaterial, and a filling material configured to fill a periphery of the cell. The metamaterial is made of a conductive organic material or a nanocarbon material. The filling material is made of a nonconductive organic material. The cell has an inductance and a capacitance. A phase of the input electromagnetic wave is changed by a change of at least one of the inductance and the capacitance. Hence, this invention can provide a flexible beamformer that has high directivity and a small insertion loss and is easy to manufacture.
