Propagation of EM Waves in metamaterials

[Vaibhav Sahu]

We have materials that have negative effective permittivity and permeability. In such materials, when the product of permittivity and permeability is negative, solving the wave equation yields a wave with a purely imaginary wave number. Does this mean complete attenuation of the wave ?

Maybe this review helps (I'm not an expert in this topic, but at a first glance this looks quite understandable):
