Abstract :
It has been shown that stringent requirements on permeability and permittivity are needed for surface waves to exist on the surface of the vacuum and the medium made from negative-index materials (NIM). In this paper, we theoretically analyzed the transverse magnetic modes on the surface of a finitely thick NIM plate, and examined theoretical predictions with particle-in-cell simulations. The results are in agreement and show that the requirements could be released.
