Abstract:
The existence of passive metamaterials, in which the speed of light is greater than its speed in vacuum, is proposed. Analysis and numerical simulations demonstrate these trans-vacuum-speed (TVS) properties. A transmission line realization of a TVS medium is established. Excellent agreement between the results of the theoretical constructs and the corresponding transmission line models are demonstrated. A practical transmission line TVS metamaterial design is proposed and validated numerically, which could be used to confirm these results experimentally.

Electromagnetic Waves in Matter
Consider the electromagnetic wave passing through a dielectric medium. In such a case, Maxwell's equations get modified. In Ampere's law, ε0 , the dielectric permittivity of free space is replaced with ε, the permittivity of dielectric. Also, the vacuum permeability μ0 is replaced by the permeability of the medium, μ.
Furthermore, the...
