A Double-Layer Chiral Metamaterial with Negative Index

Giant Circular Dichroism and Negative Refractive Index of Chiral Metamaterial Based on Split-Ring Resonators

“…MMs have become an excellent platform for some unique applications, such as superlens, cloaking, electric devices, and so on [2][3][4][5]. Recently, more and more interest has been focused on the chiral metamaterial (CMM) structures due to their attractive EM (optical) properties such as strong optical activity, circular dichroism (CD) and negative refractive index (NRI) from microwave to optical range [6][7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22]. Intuitively, CMMs cannot be brought into congruence with their mirror images (the socalled enantiomer), which neither violates reciprocity nor time-reversal symmetry.…”

Terahertz Metamaterial Modulators Based on Absorption

“…Metamaterials have produced many exotic effects such as negative refraction [1][2][3][4], zero refractive index [5][6][7][8], sub-wavelength imaging superlens [9], electromagnetic cloaking [10][11][12][13]. The novel properties of metamaterials come from the artificial atoms which can flexibly tailor the electric and magnetic response.…”

Application of Chiral Layers and Metamaterials for the Reduction of Radar Cross Section

“…During the past several years, chiral metamaterials as a kind of artificial materials has attracted an enormous amount of interest that could be used to achieve many customized functionalities, such as the negative refraction and giant optical activity [10][11][12][13][14][15][16][17][18][19][20], and many other applications [21][22][23][24][25][26][27][28][29][30][31][32][33][34][35][36][37][38]. The constitutive equations for chiral media assuming a time harmonic dependence e jωt are [1]:…”
