Abstract

The paper is devoted to experimental and theoretical investigation of the spectral characteristics of anisotropic wire metamaterials. The wire metamaterial is a two-dimensional array consisting of thin copper wires, having wire diameter of 0.2 mm. Transmission spectrums with clearly expressed plasma frequency are obtained. Microwave range with a negative effective permittivity is located below than plasma frequency. The measured spectrums have a good agreement with the theoretical simulations in the millimeter waveband. Investigations were carried out in the frequency range 22-40 GHz. Theoretically shown possibility of effective management of the transmission spectrum of a wire medium with a magnetic filling by changing the external magnetic field near the electron magnetic resonance.
