Refraction Characteristics of Cold Plasma Thin Film as a Left-Handed Metamaterial

A methodical analysis of refraction characteristics of a plane wave with any arbitrary polarization by a cold plasma thin film as a left-handed metamaterial (CPTF-LHM) which has simultaneously negative permittivity and permeability is presented. Numerical calculations are performed by the transfer matrix method using an in-house developed simulation program code. The results strongly recommend a possibility of manufacturing anti-reflection and/or total-transmission coatings and filters for a wide frequency range and/or by tuning the fraction of thickness of the CPTF-LHM.
