An infrared (IR) tunable perfect meta-absorber (TPM) is presented, which configured of metal-insulator-metal (MIM) structure. The unit cell the TPM device composed two opposite T-shaped and rod-shaped Au resonators on reflective mirror layer. optimized feature size can achieve absorption resonant wavelength be tuned from blue-shift first then red-shift by increasing gap between continuously. tuning process red shift linear. By changing distance resonators, exhibits linearly. Moreover, shows polarization-dependent characteristic that main resonance attenuated 100% to 0% polarization angle 0° 90° incident IR light. has an excellent linear relationship with ambient refractive index, sensitivity maximum figure merit (FOM) are calculated as 1249 nm/RIU 21 RIU−1, respectively. These results prove design proposed very suitable for use sensing, switching, index sensing applications.

Abstract In this study, a phase of metasurface is proposed based on rotational ring configuration, whose tuning principle associated with its conversion between spin angular and orbital momentum. The focusing vortex beams could be obtained steerable focal plane. spin‐selection mechanisms shifting process depend the corresponding momentums. To promote practical application, relationships mechanical performance, i.e., limited circumvolution angle optical properties including range length momentum are analyzed discussed, indicating that demand implementation would lower by increasing converted sparse aperture then demonstrated as an effective solution to implement involved high This work will pave way for designing tunable facilitating their applications in areas manipulation vortex‐based communication.
