Planar Slab of Chiral Nihility Metamaterial Backed by Fractional Dual/Pemc Interface

Abstract

Abstract-Fields inside the chiral nihility slab which is backed by perfect electric conductor are determined. It is noted that both electric and magnetic fields exist inside the grounded chiral nihility slab when it is excited by a plane wave. Electric field inside the slab disappears for excitation due to an electric line source. Magnetic field inside the slab disappears when geometry changes to corresponding dual geometry. Dual geometry means chiral nihility slab backed by perfect magnetic conductor and excited by a magnetic line source. Using fractional curl operator, fields are determined for fractional order geometries which may be regarded as intermediate step between the two geometries which are related through principle of duality. Discussion is extended for chiral nihility slab which is backed by perfect electromagnetic conductor (PEMC).

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]:…”

Exotic Characteristics of Power Propagation in the Chiral Nihility Fiber

“…Chiral nihility metamaterial is a special case of chiral negative refraction medium, in which the permittivity and permeability are simultaneously zero [25,41]. Waves in the chiral nihility metamaterial waveguides have also been examined in literature [42][43][44][45] and our previous papers [46,47]. Although chiral fibers have been investigated during the last two decades due to their potential applications in optical communications, optical sensors and integrated optics devices [48][49][50][51], chiral nihility fiber has not been studied yet.…”

Surface Wave Modes in Chiral Negative Refraction Grounded Slab Waveguides

“…Chiral nihility metamaterial is a special case of chiral negative refraction medium, in which the permittivity and permeability are simultaneously zero [26,39]. Waves in the parallel-plate waveguide containing two-layer chiral nihility metamaterials and one air layer [40] and in the chiral nihility metamaterial grounded slab [41][42][43] have been examined.…”
