MODE CONTROL FOR SYSTEM OF COUPLED SPLIT-RING RESONATORS BY MEANS OF LIGHT
Read the full article
The article deals with implementation of magnetic metamaterials in microwave frequency range tunable by means of light. Characteristics of a split-ring resonator with integrated voltage variable capacitor for frequency re-tuning, and a photodiode, for applying a DC bias, dependent on illumination are investigated. It is shown, that illumination change shifts the resonant response of the resonator up or down in frequency depending on the photodiode polarity. A system of coupled split-ring resonators is considered and system's response splitting is shown to the clear (bright) and fuzzy (dark) modes by means of light.
