Abstract

The progress in developing metallic metamaterial lenses founded on stacked subwavelength hole arrays is reported. Before, the lens was studied when it emulates a medium with effective index of refraction -1. Here, the lens is investigated at higher frequencies, where it behaves like a near-zero index of refraction. We show that exploiting both regimes, dual-band capabilities are attainable. Moreover, a zoning technique is applied to the initial design to reduce the lens in terms of volume and weight, while the performance is maintained.
