Design and measurement of negative permeability metamaterials made from conductor-coated high-index dielectric inclusions

Recent progress in some composite materials and structures for specific electromagnetic applications

“…High dielectric constant materials, as well as a combination of conductors and dielectric materials, can also be used as artificial magnetic metamaterials with real effective permeability m.1. [386][387][388] However, the effective permeability and resonance effect of above mentioned metamaterials without using magnetic components is rather small. To amplify the inductive behaviour of meatmaterials, it is necessary to use magnetic components.…”

Experimental measurement of negative index in an all-dielectric metamaterial

“…Effective resonant permeability having negative values has been retrieved from measurements from high permittivity ceramic cubes or rods. 5,9,12,14 Until now, negative index has been most often achieved adding metallic inclusions to the HPR in order to get the necessary negative permittivity. 7,10,12 In this letter, we report a negative index ADM, that is, it involves resonant effective permeability and permittivity issued from the first two modes of Mie resonances of HPR.…”

Permeability enhancement of soft magnetic films through metamaterial structures

“…Among many other results, the production of materials with large permeability levels and without any conventional magnetic constituents such as ferrite or ferromagnetic materials has been demonstrated [4][5][6][7][8]. Conventional magnetic materials have been used in conjunction with metamaterial patterns in various ways [9,10], and in particular, magnetic cores made of ferrite or ferromagnetic wires [11,12] have been shown to boost the permeability levels attainable in magnetic metamaterials.…”
