The scattering variety [PDF]

open access: yesJournal of High Energy Physics, 2014
The so-called Scattering Equations which govern the kinematics of the scattering of massless particles in arbitrary dimensions have recently been cast into a system of homogeneous polynomials. We study these as affine and projective geometries which we call Scattering Varieties by analyzing such properties as Hilbert series, Euler characteristic and ...

Asymmetric propagation of spoof surface plasmons along doubly corrugated metal surfaces

open access: yesAIP Advances, 2020
Spoof surface plasmons (SSPs) on the doubly corrugated metal surfaces can find a variety of applications, such as waveguides, filters, sensors, communications, and other high-performance active devices in terahertz (THz) and microwave bands.

Abrupt bifurcations in chaotic scattering : view from the anti-integrable limit [PDF]

open access: yes, 2013
Bleher, Ott and Grebogi found numerically an interesting chaotic phenomenon in 1989 for the scattering of a particle in a plane from a potential field with several peaks of equal height.

Linewidths in bound state resonances for helium scattering from Si(111)-(1x1)H [PDF]

open access: yes, 2009
Helium-3 spin-echo measurements of resonant scattering from the Si(111)–(1 × 1)H surface, in the energy range 4–14 meV, are presented. The measurements have high energy resolution yet they reveal bound state resonance features with uniformly broad ...

Inherent Relations among the Three Representations of Radar Target Angular Glint (in English)

open access: yesLeida xuebao, 2014
Based on ElectroMagnetic (EM) theory and the monopulse radar angle measurement principle, the formulae of angular glint for complex target are proposed and generally applied to tackling practical problems.

Dispersion Theory of Surface Plasmon Polaritons on Bilayer Graphene Metasurfaces

open access: yesNanomaterials, 2022
Surface plasmon polaritons (SPPs) on the graphene metasurfaces (GSPs) are crucial to develop a series of novel functional devices that can merge the well-established plasmonics and novel nanomaterials.

Advancing neutron diffraction for accurate structural measurement of light elements at megabar pressures

open access: yesScientific Reports, 2023
Over the last 60 years, the diamond anvil cell (DAC) has emerged as the tool of choice in high pressure science because materials can be studied at megabar pressures using X-ray and spectroscopic probes.

Theoretical and Experimental Study on the Permittivity of CdTe in the Terahertz Band

open access: yesLeida xuebao, 2018
The phonon dispersion spectrum, eigenvector, and lattice vibration frequency of cadmium telluride with a zinc blende structure have been investigated using the density functional theory, and the permittivity of cadmium telluride crystal is numerically ...

Ultrathin MWCNT/Ti3C2Tx Hybrid Films for Electromagnetic Interference Shielding

open access: yesNanomaterials
The disordered assembly and low conductivity of carbon nanotubes are the main problems that limit the application of electromagnetic interference (EMI) shielding. In this work, an ordered lamellar assembly structure of multiwalled carbon nanotube/Ti3C2Tx
