Nonreciprocal Scattering by PT-symmetric stack of the layers
, 2015 The nonreciprocal wave propagation in PT-symmetric periodic stack of binary dielectric layers characterised by balances loss and gain is analysed. The main mechanisms and resonant properties of the scattered plane waves are illustrated by the simulation ...

Response of Composite Beam Structure under Unbalanced Excitation of Rice Threshing System
Shock and Vibration, 2022 This paper studies the dynamic response of the support beam under the unbalanced excitation of the rice threshing system. The differential equation of motion of the supporting beam under the action of harmonic force is established by the modal ...

Decay of polarized muon at rest as a source of polarized neutrino beam [PDF]
, 2007 In this paper, we indicate the theoretical possibility of using the decay of polarized muons at rest as a source of the transversely polarized electron antineutrino beam. Such a beam can be used to probe new effects beyond standard model.

Circular symmetric Airy beam with the inverse propagation of the abruptly autofocusing Airy beam [PDF]
arXiv, 2020 In this letter, we introduce a new class of light beam, the circular symmetric Airy beam (CSAB), which arises from the extensions of the one dimensional (1D) spectrum of Airy beam from rectangular coordinates to cylindrical ones. The CSAB propagates at initial stages with a single central lobe that autofocuses and then defocuses into the multi-rings ...

Even-odd effect in higher-order holographic production of electron vortex beams with nontrivial radial structures [PDF]
Phys. Rev. A99, 013608 (2019), 2019 Structured electron beams carrying orbital angular momentum are currently of considerable interest, both from a fundamental point of view and for application in electron microscopy and spectroscopy. Until recently, most studies have focused on the azimuthal structure of electron vortex beams with well-defined orbital angular momentum.
