Abstract: Abstract Reflection and transmission characteristics of a planar interface, of non-integer dimensional (NID) dielectric-chiral mediums, are studied for oblique incident electromagnetic linearly polarized plane wave. For this purpose, reflected power for parallel and perpendicularly polarized… read more here.

DOI: 10.3390/photonics10040401
Abstract: Structural color is anticipated to replace pigmented or chemical color due to its superior saturation, resolution, environmental friendliness, and longevity. We achieve a full-color gamut of structural colors and anti-counterfeit functions by an all-dielectric chiral… read more here.
