“…For the metamaterial in region 3 we will employ a non-dispersive metamaterial with  and  given by The dependence of 3  on  for the metamaterial in Region 3 is taken into account [2][3][4][5][15][16][17], it is considered by [10,11] and a = d [10]. In this case R = 0 (minimum) and T = 1 (maximum) for any frequency and for any angle of incidence (Figure 4).…”

We investigate the characteristics of electromagnetic wave reflection and transmission by multilayered structures consisting of a pair of left-handed material (LHM) and dielectric slabs inserted between two semi-infinite dielectric media. The theoretical aspect is based on Maxwell's equations and matching the boundary conditions for the electric and magnetic fields of the incident waves at each layer interface. We calculate the reflected and transmitted powers of the multilayered structure taking into account the widths of the slabs and the frequency dependence of permittivity and permeability of the LHM. The obtained results satisfy the law of conservation of energy. We show that if the semi-infinite dielectric media have the same refractive index and the slabs have the same width, then the reflected (and transmitted) powers can be minimized (and maximized) and the powers-frequency curves show no ripple. On the other hand if the semi-infinite dielectric media have different values of refractive indices and the slabs have different widths, then under certain conditions the situation of minimum and maximum values of the mentioned powers will be reversed.

“…The guidance characteristics of circular LHM rod waveguide including the dispersion properties and power confinement characteristics were studied [30]. Nonlinear waves guided by a LHM waveguide structure surrounded by a Kerr-like nonlinear dielectric was also investigated [31]. Due to the unusual properties of guided waves in LHMs, many potential applications were mentioned such as slab waveguide sensor [32][33][34][35][36][37][38] and bandpass filter [39].…”

TE guided modes at microwave frequencies in metal-left-handed material-ferrite waveguide structures are studied numerically. The effect of ferrite layer parameters on the dispersion properties of the waveguide structure is investigated in details. It is found that the modal index of the guided mode is negative as if the overall structure was left-handed material. A considerable effect of the gyromagnetic ferrite layer on the dispersion properties of the structure is observed. The power propagating in each layer is also evaluated.
