title: Existence and design of trans-vacuum-speed metamaterials.
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.
