The main findings in this research has been the unique behavior of sub-skin depth metamaterials, the critical thickness at which they start showing signatures of resonant features and then ultimately saturating at twice the skin depth of the metal used. They also show a direct conductivity dependent behavior but suffer from huge radiation losses when the metal acquires a superconducting nature. The near field coupling in metamaterials gives rise to sharp resonant features with high Q factor which has the potential to be used for thin film sensing. Dielectric over layers of as thin as 100nm shows a notable shift in the resonances of the metamaterial. Destroying the periodicity of metamaterials does not affect its resonance properties significantly. Asymmetric coupling scheme results in a sharp transparency peak which mimics the quantum phenomena of electromagnetically induced transparency.
