Optical Texture Super‐Lattices Produced by Talbot Effect at Superimposed Gratings.
Publication Type: Academic Journal
Source(s): Annalen der Physik. Mar2023, Vol. 535 Issue 3, p1-5. 5p.
Abstract: Fresnel diffraction on periodic gratings results in a two‐dimensional periodic distribution of light intensity, also known as the Talbot effect. Here this approach is extended to the family of superimposed structures with translational symmetry, which ...
Fresnel diffraction at circular cylinders.
Publication Type: Academic Journal
Source(s): International Journal of Modern Physics C: Computational Physics & Physical Computation. Mar2023, Vol. 34 Issue 3, p1-11. 11p.
Abstract: Fresnel diffraction is a fundamental wave phenomenon happening near the shadow boundary behind a large opaque object. Previously, it was studied for the case of diffraction at large apertures in a black screen. In this paper, we investigate this phenom...
Modeling and measurement of human body blockage loss at 28 GHz.
Publication Type: Academic Journal
Source(s): Journal of Electromagnetic Waves & Applications. Mar2023, Vol. 37 Issue 4, p538-548. 11p.
Abstract: Millimeter-wave (mm-Wave) spectrum is an essential enabler to the fifth generation (5G) wireless technology. Humans are one of the most noticeable blockers that cause temporal variation in indoor radio channels. This paper presents human blockage measu...
Efficient methodology with potential uses of Fresnel diffractometry for real-time study of uniaxial nematic liquid crystal phase transitions.
Publication Type: Academic Journal
