Exotic Characteristics of Power Propagation in the Chiral Nihility Fiber

Abstract

Abstract-The novel characteristics of power propagation of guided modes in the chiral nihility fiber have been investigated theoretically. The formulas of electromagnetic fields in the core and cladding for guided modes are presented in detail. The dispersion equations, energy flux and power of guided modes are derived. The numerical results are given and discussed. Some exotic features of power propagation have been found in the chiral nihility fiber.

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.…”

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]:…”

Chiral and/or Chiral Nihility Interfaces: Parametric Dependence, Power Tunneling and Rejection

“…Chiral nihility is an emerging area and a lot interesting application are discussed, such as surface wave modes in grounded chiral nihility waveguides [22,23], focusing [24], chiral fibers [25] and use of gyrotropic chiral media [26,27]. Fractional dual solution for chiral nihility metamaterials have been studied by Naqvi [28,29].…”
