Superlensing using hyperbolic metamaterials: the scalar case

TL;DR

This paper explores superlensing with hyperbolic metamaterials, proposing two object-independent schemes that overcome size and wavelength constraints, despite the complex modeling challenges posed by their changing equation types.

Contribution

It introduces two novel superlensing schemes using hyperbolic metamaterials that do not depend on object size or wavelength, advancing the design of versatile imaging devices.

Findings

Proposed object-independent superlensing schemes.

Analyzed the mathematical models with changing elliptic and hyperbolic equations.

Demonstrated potential for imaging arbitrary objects without size or wavelength restrictions.

Abstract

This paper is devoted to superlensing using hyperbolic metamaterials: the possibility to image an arbitrary object using hyperbolic metamaterials without imposing any conditions on size of the object and the wave length. To this end, two types of schemes are suggested and their analysis are given. The superlensing devices proposed are independent of the object. It is worth noting that the study of hyperbolic metamaterials is challenging due to the change type of modelling equations, elliptic in some regions, hyperbolic in some others.
