Analysis of electromagnetic scattering from typical targets for orbital‐angular‐momentum waves: Theoretical model

چکیده
The target scattering characteristics in microwave band are necessary to be researched for Orbital-Angular-Momentum (OAM) wave-based radar applications. A theoretical description of electromagnetic (EM) from a typical by OAM waves is proposed this paper. First, decomposed into plane the spectral domain with different elevation and azimuth angles. Then, form each wave determined through coordinate system transformation physical optics approximation. Formulas numerical results presented OAM-based cross section perfect electric conductor dielectric plate cylinder. Unlike conventional EM scattering, properties cylinder analysed particular emphasis on mode influence. provide insights wave-matter interactions may find important applications propagation detection imaging.

Inverse Medium Scattering Problems for Electromagnetic Waves
Consider a time-harmonic electromagnetic plane wave incident on a medium enclosed by a bounded domain in R3. In this paper, existence and uniqueness of the variational problem for forward scattering are established. An energy estimate for the scattered field with a uniform bound with respect to the wavenumber is obtained in the case of low frequency on which the Born approximation is based. A c...
متن کاملA New Theorem Concerning Scattering of Electromagnetic Waves in Multilayered Metamaterial Spherical Structures
The proposed theorem in this paper is indicative of a kind of duality in the propagation of waves in the dual media of and in the spherical structures. Independent of wave frequency, the number of layers, their thickness, and the type of polarization, this theorem holds true in case of any change in any of these conditions. Theorem: Consider a plane wave incident on a multilayered spheric...
