Abstract

The dispersion characteristics of asymmetric double-negative material slab waveguides have been investigated by using normalized parameters. The results show that the dispersion characteristics of these material waveguides differ dramatically from conventional guided waves, and they possess a number of unusual properties, including the absence of fundamental modes, propagation of the first-order mode within narrow frequency ranges, and the existence of modes for imaginary transverse wave numbers, for example. In particular, for one fast wave mode, near cutoff, one normalized frequency corresponds to two possible propagation coefficients.
