Abstract

Using active loads in circuits that result in negative differential resistances at various nodes in the circuit are used for producing resistance cancellation, gain, oscillations, and other types of effects not seen in passive circuits. We aim to demonstrate these properties in metamaterial unit cells with the hope of mimicking the circuit behavior in bulk media. In the metamaterial unit cells, we were able to experimentally show resistance cancellation by controlling the quality of the resonance of the unit cell, oscillation and harmonic generation in the unit cell, and mixing within the unit cell between incident signals and the self generated oscillations and harmonics.
