All-dielectric scale invariant waveguide [PDF]
Nature Communications, 2023 Total internal reflection (TIR) governs the guiding mechanisms of almost all dielectric waveguides and therefore constrains most of the light in the material with the highest refractive index.

All-Dielectric Gratings with High-Quality Structural Colors [PDF]
Nanomaterials, 2023 We present a dual-layer hafnium dioxide (HfO2) grating capable of full-color modulation in the visible spectrum by leveraging the magnetic dipole resonance induced by the lower-layer HfO2 grating, while the upper-layer HfO2 grating serves as a refractive

All-dielectric electromagnetically induced transparency-like metasurface with breaking symmetric
Materials Research Express, 2022 We investigate an all-dielectric metasurface to mimic the electromagnetically induced transparency-like phenomenon in the microwave. The unit cell is comprised of two hollow split ring resonators with different parameters, which form an asymmetric ...
