Abstract: The work investigated metamaterials of the centimeter range of electromagnetic waves. The elements that make up their structure are long conductive rods (${l\gg\lambda}$) and half-wave vibrators (${l\approx\lambda/2}$). In the wavelength region of large lengths of half-wave vibrators, an equivalent model of parallel resonant oscillator circuit was used to describe their interaction with radiation. The transmission spectra of samples with a lattice of elements of one and a sublattice of another type were obtained. On the samples in the form of a prism, the angular dependence of the transmission of microwave radiation was studied. the effect of negative refraction is observed at the low-frequency boundary of the scattering region of electromagnetic waves by samples with the half-wave vibrators sublattice. The strong influence of changes in the structure of samples (sublattice shift) on their spectral characteristics is shown.
Keywords: electromagnetic crystal, metamaterial, left-handed media, half-wave vibrator, negative refraction.
