Hierarchical Fe-Co@TiO2 with Incoherent Heterointerfaces and Gradient Magnetic Domains for Electromagnetic Wave Absorption.

ACS Nano, 2023
Induced polarization response and integrated magnetic resonance show prosperous advantages in boosting electromagnetic wave absorption but still face huge challenges in revealing the intrinsic mechanism.

Vector diffraction theory for electromagnetic waves

Journal of the Optical Society of America A, 2001
The scalar Huygens-Fresnel principle is reformulated to take into account the vector nature of light and its associated directed electric and magnetic fields. Based on Maxwell's equations, a vector Huygens secondary source is developed in terms of the fundamental radiating units of electromagnetism: the electric and magnetic dipoles. The formulation is

Diffraction Theory of Electromagnetic Waves

Physical Review, 1939
It has been shown by Larmor, Kottler and others that the classical method of calculating diffraction from the Kirchhoff formula in terms of a scalar light function cannot be applied directly to the electromagnetic field since it takes into account neither the vector character of the field nor the effect of charges along the contour of the opening.

Diffraction of electromagnetic waves on plasma cylinders

Plasma Physics, 1967
The diffraction of electromagnetic waves on a cylindrical plasma is numerically computed. The calculations are made using the geometrical optics approximation and then the wave equation (exact solution). The electric field vector of the incident wave is taken as parallel to the axis of the cylinder.

Diffraction of Electromagnetic Waves by Small Inhomogeneities

Journal of Mathematical Sciences, 2002
The authors study two problems of diffraction of plane electromagnetic waves scattered by a small inhomogeneity in a layer and by a jump in the impedance on a small segment of the interface of two media. The paper presents some results on the asymptotic representation of the diffracted fields and Green's function.

Diffraction of electromagnetic wave on multielement diffraction grating

IEEE Transactions on Antennas and Propagation, 1997
The problem of plane-wave diffraction on a multielement grating of arbitrarily shaped cylindrical screens is rigorously solved using the integral equations technique. An integral representation of the Green's function of the problem is suggested. It substantially allows improvement of the calculation accuracy and effectiveness of solving.

Wave diffraction by a perfect electromagnetic conductor wedge

Optik (Stuttgart), 2019
The scattering of plane electromagnetic waves by a perfect electromagnetic conductor wedge is investigated. The diffraction coefficient of the wedge is obtained by considering the structure of the scattered waves by a whole perfect electromagnetic ...

Diffraction of electromagnetic waves by a multielement diffraction grating

Materials Science, 1996
A rigorously posed electrodynamical problem of diffraction of a plane wave by a multielement diffraction grating that consists of cylindrical screens with arbitrary curvature is solved by the method of integral equations. We construct an integral representation of the Green function of the problem under consideration which gives a significant increase ...

Diffractional Nonreciprocity at Electromagnetic Wave Diffraction on a Slit

Journal of Contemporary Physics (Armenian Academy of Sciences), 2018
The diffraction on a slit in a metal screen located between two media with different refractive indices was experimentally investigated. It was shown that being a function of the wavelength the intensity of diffracting wave depends on the refractive index of medium, which the electromagnetic wave penetrates.
