Analysis of reflection and transmission from a planar NID-dispersive slab

Behavior of transmitted and reflected power from a planar non-integer dimensional lossless dispersive slab, placed in free space, is explored for uniform electromagnetic plane wave excitation. Dispersion has been incorporated through the Lorentz-Drude model. As the frequency of excitation increases, the dispersive slab respectively behaves as epsilon positive, double negative, mu negative, double positive meta-material. Effects of variation of angle of incidence, width of the slab and frequency of excitation on behavior of the powers have been noted taking different values of the parameter modeling non-integer dimensional space.
