Aperiodic Diffract: Study of diffraction gratings

Modelling in Science Education and Learning, 2014
In this work we introduce a virtual laboratory, APERIODIC DIFFRACT, developed in Matlab GUI (Graphical User Interface) as an informatics tool for teaching the diffractive properties of aperiodic gratings. This GUI allows the student to  generate aperiodic sequences by iterating and lets to study the spectra for different iterating orders.<br /> ...

Determination of the angle of rotation of the diffraction grating by the method of conical diffraction

Фізика і хімія твердого тіла, 2022
Diffractograms of rotated polyaniline fiber grating were studied experimentally. Based on the obtained results, the diffraction patterns were analyzed and set of experimental data obtained after image digitization was approximated by the least squares ...

On the Intensity Distribution Function of Blazed Reflective Diffraction Gratings [PDF]

JOSA A, 31, 2179-2184 (2014), 2014
We derive from first principles the expression for the angular/wavelength distribution of the intensity diffracted by a blazed reflective grating, according to a scalar theory of diffraction. We considered the most common case of a groove profile with rectangular apex.

Mitigating the Impact of Asymmetric Deformation on Advanced Metrology for Photolithography

Applied Sciences
Controlling overlay in lithography is crucial for improving the yield of integrated circuit manufacturing. The process disturbances can cause undesirable morphology changes of overlay targets (such as asymmetric grating), which can significantly impact ...

Excitation of surface waves on one-dimensional solid–fluid phononic crystals and the beam displacement effect

AIP Advances, 2014
The possibility of surface wave generation by diffraction of pressure waves on deeply corrugated one-dimensional phononic crystal gratings is studied both theoretically and experimentally.

Phase Imbalance Optimization in Interference Linear Displacement Sensor with Surface Gratings

Sensors, 2020
In interferential linear displacement sensors, accurate information about the position of the reading head is calculated out of a pair of quadrature (sine and cosine) signals.
