TL;DR

This paper proposes a uniaxial left-handed metamaterial at microwave frequencies with reduced losses and a broader operational band by optimizing magnetic resonators without using split-ring resonators.

Contribution

It introduces a novel uniaxial LHM design combining wire lattices and optimized magnetic resonators, reducing losses and expanding bandwidth.

Findings

Significantly decreased magnetic losses.

Broadened frequency band for left-handed behavior.

Effective uniaxial LHM design at microwaves.

Abstract

In this work a possible realizations of a uniaxial variant of left-handed material (LHM) at microwaves is considered. The meta-material has some features of the known structure studied by the group of D. Smith in 2001, however in the present structure a lattice of parallel wires and a lattice of artificial magnetic resonators (MRs) are unified and the MRs are not split-ring resonators. The optimizing of MRs allows significantly decrease the magnetic losses and broaden the band within which the meta-material becomes a LHM.
