New type of lenses based upon left-handed materials

TL;DR

This paper proposes a novel lens design using left-handed materials embedded in regular materials, offering easier fabrication and potential for 3D imaging due to multiple focal points.

Contribution

It introduces a new lens type based on left-handed materials with equal refractive indices, simplifying manufacturing compared to Veselago lenses.

Findings

Lenses with larger focal lengths than the slab width are possible.

The new lenses have multiple foci, enabling 3D imaging.

They are easier to produce than Veselago lenses.

Abstract

New type of lenses which are a slab of a left-handed material embedded into a regular material is proposed. These two materials should have equal refractive indices. Lenses with a focal length larger than the width of the slab can be constructed. These lenses should be easier to make than the well known Veselago lens, because the materials of the Veselago lens should obey an additional matching condition. Lenses of new type have multiple foci and might be useful for the 3D imaging.
