Fundamental Limits on Spatial Resolution in Ultrafast X-ray Diffraction

open access: yesApplied Sciences, 2017
X-ray Free-Electron Lasers have made it possible to record time-sequences of diffraction images to determine changes in molecular geometry during ultrafast photochemical processes.

Low-frequency plane wave diffraction on a two-layer grating [PDF]

open access: yesSerbian Journal of Electrical Engineering, 2004
In this paper the problem of TE and TM plane wave diffraction from a two-layer grating in low-frequency case is presented. The problem is solved using the network model.

Analytic expressions and approximations for the on-axis, aberration-free Rayleigh and Debye integral in the case of focusing fields on a circular aperture [PDF]

open access: yesJournal of the European Optical Society-Rapid Publications, 2008
We present a derivation of the analytic result for on-axis field values of the Rayleigh diffraction integral, a result that was originally presented in a paper by Osterberg and Smith (1961).

Optical Assembling of Micro-Particles at a Glass–Water Interface with Diffraction Patterns Caused by the Limited Aperture of Objective

open access: yesApplied Sciences, 2018
Optical tweezers can manipulate micro-particles, which have been widely used in various applications. Here, we experimentally demonstrate that optical tweezers can assemble the micro-particles to form stable structures at the glass–solution interface in ...

DIFFRACTIVE PHENOMENA [PDF]

open access: yesLepton-Photon 01, 2002
The most recent theoretical and experimental results in the field of diffractive scattering are reviewed. A parallel between the two current theoretical approaches to diffraction, the DIS picture in the Breit frame and the dipole picture in the target frame, is given, accompanied by a description of the models to which the data are compared.

Investigating Far-Field Spectra and Near-Field Features of Extraordinary Optical Transmission Through Periodic U- to H-Shaped Apertures

open access: yesIEEE Photonics Journal, 2012
By exploiting the in-house finite-difference time-domain (FDTD) program, the optical properties of a designated 2-D array of U- to H-shaped holes perforated on a metallic film are analyzed.

Numerical Simulation of a Novel Sensing Approach Based on Abnormal Blocking by Periodic Grating Strips near the Silicon Wire Waveguide

open access: yesSensors, 2018
This paper discusses the physical nature and the numerical modeling of a novel approach of periodic structures for applications as photonic sensors. The sensing is based on the high sensitivity to the cover index change of the notch wavelength.
