Near-field Meta-optics
Dongyoung Lee, Sehwan Kim, Jisoo Kyoung
Metasurfaces have revolutionized compact wavefront control using planar, subwavelength structures. However, conventional meta-optical devices predominantly operate within a far-fie…
Refractive Index Robustness of Metalenses
Dongyoung Lee, Jisoo Kyoung
Metalenses have emerged as a powerful platform for compact wavefront engineering; however, their performance stability under refractive index fluctuations induced by environmental…
A Thickness Dependent Enhancement of Optical Resolution in the Vicinity of an Epsilon-near-zero Slab
Young-Rok Jang, Soo Bong Choi, Doo Jae Park +1
Recent studies reports that an epsilon-near-zero (ENZ) thin slab between a specimen and a substrate contributes in enhancing the spatial resolution of the optical system. Here, we…
Terahertz nano antenna enabled early transition in VO2
Young-Gyun Jeong, Ji-Soo Kyoung, Jae-Wook Choi +6
We study terahertz transmission through nano-patterned vanadium dioxide thin film. It is found that the patterning allows the lowering of the apparent transition temperature. For t…
