wave through a double-negative slab

Reflected and transmitted powers due to the interaction of electromagnetic waves with a double-negative slab are investigated in detail. The formulations for the transverse electric wave case are provided. Transfer matrix method is used in the analysis to find the reflection and the transmission coefficients at each interface. Numerical results are presented for both transverse electric and transverse magnetic wave cases to show the effect of the structure parameters, the incidence angle and the frequency on the reflected and the transmitted powers
