Document Type and Number:
Japanese Patent JP6911932
Kind Code:
B2
Abstract:
The present invention provides a polarization control plate including n layers (n≥4) of overlapping admittance sheets (10-1 to 10-6) each of which includes a plurality of plane unit cells, in which an admittance of a first plane unit cell included in an admittance sheet in a layer a (1≤a≤n) and an admittance of a second plane unit cell being included in an admittance sheet in a layer b (1≤b≤n and b≠a) and overlapping the first plane unit cell are different from each other, and an admittance of the plane unit cell in an x direction and an admittance of the plane unit cell in a y direction are different from each other.
