Helicity Maximization Below the Diffraction Limit
Mina Hanifeh, Mohammad Albooyeh, Filippo Capolino
Optimally-chiral electromagnetic fields with maximized helicity density, recently introduced in [1], enable chirality characterization of optically small nanoparticles. Here, we de…
Helicity Density Maximization in a Planar Array of Achiral High-Density Dielectric Nanoparticles
Mina Hanifeh, Filippo Capolino
We investigate how a periodic array composed of achiral isotropic high-refractive index dielectric nanospheres generates nearfield over the array surface reaching helicity density…
Helicity Maximization of Structured Light to Empower Nanoscale Chiral Matter Interaction
Mina Hanifeh, Mohammad Albooyeh, Filippo Capolino
Structured light enables the characterization of chirality of optically small nanoparticles by taking advantage of the helicity maximization concept recently introduced in[1]. By r…
Optimally Chiral Electromagnetic Fields: Helicity Density and Interaction of Structured Light with Nanoscale Matter
Mina Hanifeh, Mohammad Albooyeh, Filippo Capolino
We propose the concept of helicity maximization applicable to structured light and obtain a universal rela-tion for the maximum of helicity density at a given field energy density.…
