Title:
REFLECTION STRUCTURE, METHOD FOR MANUFACTURING REFLECTION STRUCTURE, AND FREQUENCY-SELECTIVE REFLECTION PLATE SET
Document Type and Number:
WIPO Patent Application WO/2024/005011
Kind Code:
A1
Abstract:
The present disclosure provides a reflection structure comprising a frequency-selective reflection plate that reflects a specific frequency band of electromagnetic waves in a different direction than a regular reflection direction. The reflection structure comprises a base material with a first alignment mark, and a plurality of the frequency-selective reflection plates that are disposed side-by-side on one surface of the base material. The distance between the adjacent frequency-selective reflection plates is less than 1/2 the wavelength of the electromagnetic waves.
