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…
Illusion Mechanisms with Cylindrical Metasurfaces: A General Synthesis Approach
Mahdi Safari, Hamidreza Kazemi, Ali Abdolali +2
We explore the use of cylindrical metasurfaces in providing several illusion mechanisms including scattering cancellation and creating fictitious line sources. We present the gener…
Simultaneous Perfect Bending and Polarization Rotation of Electromagnetic Wavefront using Chiral Gradient Metasurfaces
Hamidreza Kazemi, Mohammad Albooyeh, Filippo Capolino
We introduce chiral gradient metasurfaces that allow perfect transmission of all the incident wave into a desired direction and simultaneous perfect rotation of the polarization of…
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.…
Functional metasurfaces: Do we need normal polarizations?
Sergei A. Tretyakov, Do-Hoon Kwon, Mohammad Albooyeh +1
We consider reciprocal metasurfaces with engineered reflection and transmission coefficients and study the role of normal (with respect to the metasurface plane) electric and magne…
