With an increase in the size and shape complexity of optical surfaces, the periodic structure on the optical surface can have significant effects on the beam profile, which propagates in the optical system. This necessitates a quantitative analysis o
The experimental and theoretical investigations of attosecond pulses diffraction describe one unexpected parabolic deformation of their intensity profile at few diffraction lengths. This deformation was called by some authors λ3 diffraction. In our

[EN] In this work, we report the focusing effect of a 2D sonic crystal cuboid. The proposed sonic composite lens is vertically extended from a 2-D flat Phononic Crystal Structure, but it is found to be able to focus waves in a three-dimensional manne

[EN] In this letter, the improvement in focus by the use of a pupil mask produced in an acoustic mesoscale cuboid particle ¿lled with CO2 is reported. Thereby, the result shows that the pupil mask increases the sound intensity and also increases the

In this chapter, a spatial–spectral correspondence relationship is introduced, which can be applied to monochromatic light diffraction or propagation. The conditions that make this relationship valid are discussed and its mathematical forms in the

Methods are presented for aligning the pivot point of a precessing electron probe in the scanning transmission electron microscope (STEM) and for assessing the spatial resolution in scanning precession electron diffraction (SPED) experiments. The ali

The feasibility of an alternative data acquisition strategy to improve the efficiency of beam time usage with neutron strain scanner instruments is demonstrated. By performing strain measurements against set statistical criteria, rather than time, no

A surprisingly large number of known distinct sets of light patterns propagate in free space essentially unchanged. These sets of light patterns (intensity distributions of the electric–magnetic fields) can be divided into two groups: light Waves a

The computation of flow-induced noise at low Mach numbers usually relies on a two-step hybrid methodolgy. In the first step, an incompressible fluid dynamics simulation (CFD) is performed and an acoustic source term is derived from it. The latter bec
