Artificial metamaterials and radio tomography

Abstract

538.56Results of theoretical and experimental investigations of artificial metamaterials based on composite of straight and circular conductors for radio wave range are presented. It is demonstrated that for small conductor sizes, nonresonant character of metamaterial properties of the artificial medium is retained. The possibility of application of metamaterials for increasing resolution in radio tomography is discussed.

Decrease Radar Cross-Section Objectives Using the Metamerial

“…On the basis of numerical model operations on interaction of an electromagnetic radiation with structure from elemental annuluses [2,3], the experimental model of metamaterial is created. The exemplar was executed in the form of matrix structure from the ring conductors located in frothed polystyrene.…”

Near-Field Interaction of Closed Cells for Metamaterial Creation

“…Previously, the authors of this work presented the possibility of metamaterial creation for the radio range as an artificial composite medium made up of a certain oriented linear and circular conductors [3,4]. Such a medium may have a negative refractive index.…”

“…Veselago predicted the unique properties of materials with a negative real part of the permittivity and permeability [1]. Later, a special interest was aroused by the works of D. Pendry of the possibility of developing "superlenses" allowing overcoming the diffraction limit [2].Previously, the authors of this work presented the possibility of metamaterial creation for the radio range as an artificial composite medium made up of a certain oriented linear and circular conductors [3,4]. Such a medium may have a negative refractive index.…”

Model of Broadband Metamaterial for Microwaves

“…In the previous publications [4,5] authors showed a possibility of creation of metamaterials from the selfcontained ring conductors focused definitely, placed in polystyrene foam. Creation of such structures processes the long-lived and laborious.…”
