Abstract
In this paper, we present a novel compact left-handed material unit, which can generate the equivalent negative permittivity and negative permeability in the two-dimensional direction only by etching one side of the dielectric substrate. We propose a new formula for calculating the field and circuit to analyze the equivalent permittivity and the equivalent permeability that are used to explain the principle of the left-handed characteristic of the unit. In the simulation, the equivalent permittivity and permeability are calculated by the Nicolson-Ross-Weir method, and the negative refraction is verified by the prism experiment. The experiments show that the cross-ring structure unit can present left-handed properties with frequency bands appearing at 6.86.9 GHz in the two-dimensional incidence. The left-handed material can be used to design microwave field for its simple fabrication process.
