On Negative Index Metamaterial Spacers and Their Unusual Optical Properties

Abstract

Abstract-We theoretically investigate the possibility of using a metamaterial structure as a spacer, named as metaspacer, which can be integrated with other materials in microfabrication. We show that such metaspacers can provide new optical behaviors that are not possible through conventional spacers. In particular, we investigate negative index metaspacers embedded in fishnet metamaterial structures and compare them with conventional fishnet metamaterial structures. We show that the negative index metaspacer based fishnet structure exhibits intriguing inverted optical response. We also observe that the dependence of the resonance frequency on the geometric parameters is reversed. We conclude with practicality of these metaspacers.

Investigation of microwave metamaterial based on H-shaped resonator in a waveguide configuration and its sensor and absorber applications

“…Similar results can be found in [31][32][33][34] with no sufficient explanation on the character of the permittivity and permeability (in terms of bilaterally-symmetric Drude and Lorentz models). [31][32][33][34] In this manner, these findings and explanations provide another added value to the present study.…”

Review of near-field optics and superlenses for sub-diffraction-limited nano-imaging

“…[2][3][4][5][6] This resolution was extended further by apertureless SNOM systems, which employed a nanoscale scattering probe in the near-field instead of a subwavelength aperture. [7][8][9][10][11][12][13][14] At the turn of the new millennium, imaginative new approaches for controlling electromagnetic waves began to appear for imaging, [15][16][17][18][19][20][21][22][23] photovoltaics, [24][25][26] quantum information processing and simulations, [27][28][29][30][31] wireless communications, 32,33 and novel optical materials, [34][35][36][37][38][39][40] among many others. The advent of metamaterials with simultaneously negative permittivity and permeability 41 brought renewed interest in the properties of left-handed materials first proposed by Veselago,42 which Pendry demonstrated could be applied to sub-diffraction-limited imaging with his "perfect lens."…”

Magnetic Response and Negative Refraction at Optical Frequencies on the Basis of Electronic Transitions in Rare-Earth Ions Doped Crystals

“…However, the magnitude of negative refractive index is a little smaller and its bandwidth is also much narrower compared to negative refraction materials based on metallic periodic structures [35][36][37]. According to Eqs.…”
