Title:
POLARIZATION CONTROL PLATE
Document Type and Number:
WIPO Patent Application WO/2019/082231
Kind Code:
A1
Abstract:
According to the present invention, there is provided a polarization control plate in which: admittance sheets (10-1 to 10-6) of n layers (n ≥ 4), each of which includes a plurality of planar unit cells, are overlapped; the admittance of a first planar unit cell included in the admittance sheets of a layers (1 ≤ a ≤ n) and the admittance of a second planar unit cell that is included in the admittance sheets of b layers (1 ≤ b ≤ n, and b ≠ a) and that overlaps the first planar unit cell are mutually different; and in the planar unit cells, the x direction admittance and the y direction admittance are mutually different.
