Transparent electromagnetic waves controlling member

Abstract

The present disclosure provides a transparent electromagnetic waves controlling member transmitting visible light and controlling a reflection direction or a transmission direction of electromagnetic waves in a particular frequency band, the transparent electromagnetic waves controlling member comprising: a dielectric substrate transmitting visible light; a plurality of resonant elements placed on at least one surface of the dielectric substrate, transmitting visible light and resonating with the electromagnetic waves; and a dummy pattern placed on at least one surface of the dielectric substrate, placed in a region other than a region where the plurality of resonant elements is placed, and transmitting visible light, wherein a size of the dummy pattern is 0.1 times or less of a wavelength of the electromagnetic waves.
