Structural full-color modulation metasurfaces for dynamic visible cryptography |
| 초록 |
High refractive index dielectric metasurfaces have offered interesting way to manipulate light with Mie resonances. Interference of electric and magnetic mode within dielectric nanoparticles give opportunity to control directional scattering and propagation direction of light. The resonant frequencies can be tuned by varying the dimension, thereby enabling simultaneous manipulation of the point where Kerker's 1st and 2nd condition are satisfied. In this research, we suggest high index all dielectric metasurfaces with tunable full color generation and microcryptography application. The unit nanoparticle that has asymmetry response differently at horizontally and vertically polarized light. This interesting behavior can be utilized for microcryptography application. |
