| Second-Harmonic Generation and Spectrum Modulation by Active Nonlinear Metamaterial (2009) | |||||||||
Abstract | |||||||||
| The nonlinear properties of a metamaterial sample composed of double-layer metallic patterns and voltage controllable diodes are experimentally investigated. Second harmonics and spectrum modulations are clearly observed in a wide band of microwave frequencies, showing that this kind of metamaterial is not only tunable by low DC bias voltage, but also behaves strong nonlinear property under a small power incidence. These properties are difficult to be found in normal, naturally occurring materials.. Comment: 14 pages, 4 figures | |||||||||
