Long‐Range Polariton Canalization in a Graphene‐Nanoribbon–Covered MgTeMoO6 Metasurface
Nanophotonics, Volume 15, Issue 9, 13 May 2026.Simulated Re(Ez) field distributions at ω = 924 cm−1 for the graphene grating, MgTeMoO6 grating, the proposed hybrid structure, and the corresponding IFCs in (kx, ky) space are shown. Re(Ez) field maps in the x–y plane at ω = 924 cm−1 for Ef = 50, 70, 74, 76, 80, and 88 meV.

Image encryption lossless recovery method based on QR code and arithmetic coding
Journal of Applied Optics, 2020 The QR code is introduced into the optical image encryption system as a data container, which can remove the speckle noise generated by the optical system when the image decryption is carried out, so that the decrypted image can be restored without loss. It is a very ideal and practical method for removing the noise. However, due to the limited storage
