“…16 However, the extra contribution to permeability from the excitation of magnetic component of microwave field along the additional wire array should be also considered. 17 Thus transmission of the 3 mm orthogonal microwire array composite can be eased through the improved impedance match, taken into account that Z = (/) 1/2 . This enables the possibility of quantitatively controlling transmittance in the orthogonal array composite through the addition of vertical wires.…”

The microwave properties of glass-fibers reinforced polymer composite embedded with an orthogonal array of Fe 77 Si 10 B 10 C 3 microwires have been investigated. The composites containing orthogonal wire arrays display a remarkable transmission window in the frequency band of 1 to 6GHz under zero external magnetic field indicating an intrinsic double-negative-index characteristic.The polymer matrices have proved to exert a synergistic effect on the microwave properties, which is responsible for the disappearance of the transmission windows when E k is perpendicular to the glass fiber direction. The plasma frequency of the orthogonal microwire array composite is higher than that of the parallel microwire array with identical wire spacing; this could be attributed to the enhanced microwire-wave interaction induced by the axial electrical components on the additional layer of perpendicular wires. All these features make this new kind of orthogonal microwire composites promising for potential cloaking and sensing applications.

Abstract-Here we present the rigorous electrodynamical solution of diffraction problem about the microwave scattering by a multilayered cylinder. The number and thickness of layers is not limited. We offer the solution when the central core of multilayered cylinder can be made of different isotropic materials as a metamaterial, a ceramic matter or a semiconductor as well as of a perfect metal. The isotropic coated layers can be of strongly lossy materials. The signs of the complex permittivity and complex permeability can be negative or positive in different combinations. Here we present dependencies of the scattered power of the incident perpendicularly and parallel polarized microwaves by the metamaterial-glass cylinder on signs of metamaterial permittivity as well as permeability. The glass layer absorbed power and metamaterial core absorbed power dependent on the hypothetic metamaterial permittivity and permeability signs at the wide range frequencies 1-120 GHz are also presented here. The metamaterial core of cylinder has a radius equal to 0.0018 m and the thickness of the coated acrylic-glass layer is 0.0002 m. We have found some conditions when the scattered-power has minimal values and the absorbed power by the coated acrylic glass layer is constant in a very wide frequency range. We have discovered that the glass layer absorbed power increases with increasing of the frequency at the range 1-120 GHz for both microwave polarizations.
