A numerical parameter study of chiral metamaterial based on complementary U-shaped structure in infrared region

Coupling Tai Chi Chiral Metamaterials with Strong Optical Activity in Terahertz Region

“…Many chiral structures such as inductor-capacitor circuit structure [6], planar U-shaped split ring resonators [7], and complementary bi-layer cross-wire [8] have been proposed to realize negative refraction afterward. Besides, optical activity [9,10] and circular dichroism [11] in chiral metamaterials are elaborated in many literatures as well, such as rosettes structure [12], Ushaped structure [13,14], twisted-arc structure [15], and many other unique structures [16][17][18][19].…”

Complementary Y-shaped chiral metamaterial with giant optical activity and circular dichroism simultaneously for terahertz waves

“…From microwave to optical frequencies, some complementary and extra EM (optical) properties could be explored and obtained using this principle (8,(41)(42)(43)(44). Here, based on Babinet's principle, the proposed bi-layer CYCMM is shown in Figure 1(b).…”

“…In this physical model, the surface patterned film is selected as Gold since it has the smallest loss in terahertz and higher frequency region (16). In numerical simulation, the gold film is described by the surface impedance model (44)(45)(46)(47). The middle dielectric substrate is selected as the Polyimide film due to its favourable optical properties, and the relative permittivity is 3.5(1 + 0.0027i).…”

Electromagnetic resonances and their tunability in planar metamolecules isomer

“…In recent years, many researchers devoted to the exploration of electromagnetic interaction of metallic nanostructure [4][5][6][7]. It is because that there exists similar property between the compound metallic nanostructure and its counterparts of the molecular orbits in chemistry: the bonding and anti-bonding states are formed due to the coupling of localized surface plasmon (LSP) [8].…”
