A New Method to Measure the Electron Beam Energy Spectrum [PDF]
مجله علوم و فنون هستهای, 2014 An innovative method has been used to calculate electron beam energy spectrum using depth-dose curve. The depth-dose distributions of the electron beam with different primary energies emerging from the electron accelerator were measured in water phantom ...

Theory and applications of free-electron vortex states
, 2017 Both classical and quantum waves can form vortices: with helical phase fronts and azimuthal current densities. These features determine the intrinsic orbital angular momentum carried by localized vortex states.

Quantum interference in optical fields and atomic radiation
, 2001 We discuss the connection between quantum interference effects in optical beams and radiation fields emitted from atomic systems. We illustrate this connection by a study of the first- and second-order correlation functions of optical fields and atomic ...

Integrated multi vector vortex beam generator
, 2013 A novel method to generate and manipulate vector vortex beams in an integrated, ring resonator based geometry is proposed. We show numerically that a ring resonator, with an appropriate grating, addressed by a vertically displaced access waveguide emits ...

Diffraction-Attenuation Resistant Beams: their Higher Order Versions and Finite-Aperture Generations
, 2010 Recently, a method for obtaining diffraction-attenuation resistant beams in absorbing media was developed through suitable superposition of ideal zero-order Bessel beams. In this work, we will show that such beams maintain their resistance to diffraction

Effect of Scatterering on Coherent Anti-Stokes Raman Scattering (CARS) signals [PDF]
, 2017 We develop a computational framework to examine the factors responsible for scattering-induced distortions of coherent anti-Stokes Raman scattering (CARS) signals in turbid samples. We apply the Huygens-Fresnel Wave-based Electric Field Superposition (HF-

Advanced Functional Materials, EarlyView.The highly anisotropic Fermi surface of bismuth results in variations in magnetotransport properties across different crystallographic directions, which can be characterized by studying microcrystals. To avoid the observed surface melting under room temperature Focused Ion Beam (FIB) irradiation, two low‐temperature FIB fabrication methods are proposed
