Summary :

A novel purely distributed two-dimensional (2D) planar structure with a negative refractive index (NRI) is proposed. The structure consists of a 2D periodic array of unit cells with metal patterns on the both sides of a substrate. The unit cell with the dimension of 55 mm² is designed at an operation frequency of about 5 GHz by full-wave finite element method simulations. Numerical simulations on the dispersion characteristics are carried out and NRI property of the structure is confirmed. A equivalent circuit taking into account the mutual capacitance between the adjacent ports in the unit cell is introduced, and theoretical investigations based on the equivalent circuit reveals that the anisotropy can be controlled by the mutual capacitance. A 1020 unit-cell NRI material is fabricated and the NRI property has been confirmed experimentally in excellent agreement with Snell's law.
