Microwave Imaging for Half-Space Conductors Using the Whale Optimization Algorithm and the Spotted Hyena Optimizer

open access: yesApplied Sciences, 2023
This research implements the whale optimization algorithm (WOA) and spotted hyena optimizer (SHO) in inverse scattering to regenerate the conductor shape concealed in the half-space.

Strictly convex norms and topology

open access: yes, 2010
We introduce a new topological property called (*) and the corresponding class of topological spaces, which includes spaces with $G_\delta$-diagonals and Gruenhage spaces.

Spectral theory of electromagnetic scattering by a coated sphere

open access: yes, 2017
In this paper, we introduce an alternative representation of the electromagnetic field scattered from a homogeneous sphere coated with a homogeneous layer of uniform thickness.

Scattering configuration spaces

open access: yes, 2008
For a compact manifold with boundary $X$ we introduce the $n$-fold scattering stretched product $X^n_{\text{sc}}$ which is a compact manifold with corners for each $n,$ coinciding with the previously known cases for $n=2,3.$ It is constructed by iterated blow up of boundary faces and boundary faces of multi-diagonals in $X^n.$ The resulting space is ...

Effects of Earth–Rock Dam Heterogeneity on Seismic Wavefield Characteristics

open access: yesEnergies, 2023
Earth–rock dams are typical soil–rock mixtures with high heterogeneity. Mastering the effect of dam heterogeneity on seismic wavefields is the premise of accurately detecting hidden risks in dams.

Dynamic coherent backscattering mirror

open access: yesAIP Advances, 2016
The phase of multiply scattered light has recently attracted considerable interest. Coherent backscattering is a striking phenomenon of multiple scattered light in which the coherence of light survives multiple scattering in a random medium and is ...

Angular X-ray cross-correlation analysis applied to the scattering data in 3D reciprocal space from a single crystal

open access: yesIUCrJ, 2022
An application of angular X-ray cross-correlation analysis (AXCCA) to the scattered intensity distribution measured in 3D reciprocal space from a single-crystalline sample is proposed in this work.
