On Localized "X-shaped" Superluminal Solutions to Maxwell Equations [PDF]

, 1998
In this paper we extend for the case of Maxwell equations the "X-shaped" solutions previously found in the case of scalar (e.g., acoustic) wave equations.

Nanoparticles of Ni1-x Znx Fe2 O4 used as Microwave Absorbers in the X-band [PDF]

Materials Research, 2019
Ferrites nanoparticles of Ni1-xZnxFe2O4 ferrites with x varying between 0 and 1, in steps of 0.2, were obtained by solution combustion synthesis (SCS) and dispersed in oil paint at the concentrations of 10, 20, 30 and 40% by ferrite weight of ferrite ...

Plane-wave scattering by self-complementary metasurfaces in terms of electromagnetic duality and Babinet's principle [PDF]

, 2013
We investigate theoretically electromagnetic plane-wave scattering by self-complementary metasurfaces. By using Babinet's principle extended to metasurfaces with resistive elements, we show that the frequency-independent transmission and reflection are ...

THE H-POLARIZED ELECTROMAGNETIC WAVE DIFFRACTION BY MULTI-ELEMENT PLANE SEMI-INFINITE GRATING

Radio Physics and Radio Astronomy, 2014
The H-polarized wave diffraction by multi-element plane semiinfinite periodic strip grating is considered. The problem is reduced to a nonlinear operator equation with respect to the unknown reflection operator of a structure. The equation is obtained as

Magnetic and electromagnetic properties of Fe/Fe2–3N composites prepared by high-energy ball milling

Journal of Materials Research and Technology, 2020
In this study, high-energy ball milling processes were adopted to prepare Fe/Fe2–3N composites. The phase composition and microstructure of the composites were characterized by X-ray diffraction, scanning electron microscopy and high-resolution ...

Rigorous analysis of extremely asymmetrical scattering of electromagnetic waves in slanted periodic gratings [PDF]

, 2001
Extremely asymmetrical scattering (EAS) is a new type of Bragg scattering in thick, slanted, periodic gratings. It is realised when the scattered wave propagates parallel to the front boundary of the grating.
