Effects of negative permittivity and/or permeability on reflection and transmission from planar, circular cylindrical, and fractal chiral-chiral interfaces

In this article, we present a study on the effects of negative permittivity and/or permeability on the transmission and reflection of electromagnetic waves from a variety of chiral-chiral interfaces. Specifically, three topological shapes - planar, circular cylindrical, and fractal - of the interface are considered with variety of parametric differences. For each case, the reflected and transmitted power of electromagnetic waves is determined and numerical results are given for various values, positive as well as negative, of permittivity and permeability. It has been noted that combinations of negative permittivity and/or permeability along with suitable values of chirality of two media give rise to diverse transmission/reflection characteristics, in case of planar interfaces, and change of focusing field intensity in case of circular cylindrical interface. Moreover, it is noted that the fractionality of dimensions provides yet another parameter to alter any given interface characteristics.
