Scattering from a Truncated Metamaterial Layer Hosted by a Planar PEC Structure: Uniform Asymptotic Solution and Validation Tests

Applied Sciences, 2022
This research paper proposes an analytical approach for evaluating electromagnetic scattering from a planar complex object made of a perfect electric conductor, which hosts a double negative metamaterial half-layer on the lit face. The method is based on

Cholesteryl esters of saturated fatty acids: cosolubility and fractionation of binary mixtures

Journal of Lipid Research, 1987
Factors affecting the solid state miscibility of saturated chain cholesteryl esters were determined from electron diffraction and differential scanning calorimetric measurements on a homologous series which included two types of crystal packing. Electron

Experimental limits of ghost diffraction: Popper’s thought experiment [PDF]

, 2018
Quantum ghost diffraction harnesses quantum correlations to record diffraction or interference features using photons that have never interacted with the diffractive element. By designing an optical system in which the diffraction pattern can be produced

Chemical, isotopic and gas composition of the first-year sea ice in 2013-2015 from the data of cores taken at the BARNEO drifting stations

Лëд и снег, 2019
As a result of the work performed at the BARNEO drifting stations (2013-2015 in the polar region of the Arctic ocean), a comprehensive testing was carried out and new data were obtained on the structure of one-year sea ice, its salinity, the distribution

Large Angle Forward Diffraction by Chiral Liquid Crystal Gratings with Inclined Helical Axis

Crystals, 2020
A layer of chiral liquid crystal (CLC) with a photonic bandgap in the visible range has excellent reflective properties. Recently, two director configurations have been proposed in the literature for CLC between two substrates with periodic photo ...

Diffractive scattering [PDF]

Journal of Physics G: Nuclear and Particle Physics, 2002
We discuss basic concepts and properties of diffractive phenomena in soft hadron collisions and in deep-inelastic scattering at low Bjorken-x. The paper is not a review of the rapidly developing field but presents an attempt to show in simple terms the close inter-relationship between the dynamics of high-energy hadronic and deep-inelastic diffraction.
