Description
| - V článku jsou prezentovány některé vlastnosti materiálů se zápornou permitivitou a permeabilitou, tj. se záporným indexem lomu, které jsou známy jako metamateriály. Jsou porovnány disperzní charakteristiky páskového vedení se záporným indexem lomu počítané různými metodami. Jsou prezentovány vypočtené a naměřené disperzní charakteristiky nově navrženého koplanárního vedení se zpětnou vlnou a nové verze objemového metamateriálu. Jsou navrženy jednoduché náhradní obvody těchto struktur, které vykazují záporný index lomu v širokém frekvenčním pásmu. (cs)
- Some characteristics of materials with negative permittivity and permeability, i.e., with a negative refractive index, known as metamaterials, are presented in this paper. Dispersion characteristics of left-handed parallel strips calculated by different methods are compared with each other. The calculated and measured dispersion and transmission characteristics of a newly proposed left-handed coplanar waveguide and of a novel volume metamaterial are shown. Simple equivalent circuits of both structures are presented together with elements values. The structures exhibit a negative refractive index in a wide frequency band.
