Isotropic Single Negative Metamaterials
Result description
This paper presents the application of simple, and therefore cheap, planar resonators for building 3D isotropic metamaterials. These resonators are: a broadside-coupled split ring resonator with a magnetic response providing negative permeability; an electric dipole terminated by a loop inductor together with a double H-shaped resonator with an electric response providing negative permittivity. Two kinds of 3D isotropic single negative metamaterials are reported. The first one consists of unit cells inthe form of a cube bearing on its faces six equal planar resonators with tetrahedral symmetry. In the second material, the planar resonators boxed into spherical plastic shells and randomly distributed in a hosting material compose a real 3D volumetric metamaterial with an isotropic response. The experiments prove the isotropic behavior of the cells and of the metamaterial specimens.

Isotropní metamateriály se zápornou permitivitou nebo permeabilitou
Czech description
Článek popisuje použití jednoduchých planárních resonátorů pro vytvoření 3D isotropních metamateriálů. Jsou to dělené kruhové rezonátory vytvářející zápornou permeabilitu, elektrické dipóly zakončené indukčností a rezonátory typu dvojité H zajišťující zápornou permitivitu. První materiál je tvořen buňkami ve tvaru krychle se šesti částicemi na svých stěnách. Druhý metamateriál je tvořen náhodně rozloženými rezonátorky zapouzdřenými v plastikových kuličkách. Experimenty potvrdily isotropní chování vzorkůmetamateriálů.
