Akhlesh Lakhtakia introduced term ‘nihility’ to determine a distinctive exotic state of a hypothetical lossless medium whose material parameters happen to be zero quantities [https://www.researchgate.net/publication/2167091_An_Electromagnetic_Trinity_from_Negative_Permittivity_and_Negative_Permeability].

On the other hand the theory of ‘epsilon-near-zero’ and ‘mu-near-zero’ materials is now widely used which seems to be fundamentally identical with the conception of nihility media.

Is there any principal differences in these conceptions?

Other question is: Is it correct to use term 'nihility' when describing resonant states in surface waves?
