詳細技術說明

High frequency filters and oscillator circuits utilize mechanical resonances to absorb or emit electromagnetic energy. Currently, these types of integrated circuits use piezoelectric materials that must be micromachined and tuned to achieve a desired frequency response. Generally, the resulting frequency produced is insufficient and additional circuitry is necessary to clean up the response, taking up additional space and increasing the cost of the overall circuit. Researchers at the University of California Davis have developed a hybrid high frequency vibrational metamaterial for use in optical and electrical devices. This superlattice metamaterial is composed of molecules and nanoparticles and can resonate in response to optical, plasmonic, electrical, thermal, or mechanical stimulation. By modifying the individual particles, a specific resonance can be achieved between 100 MHz to 2 THz. Moreover, the metamaterial exhibits a high quality factor (Q Factor), improving power efficiency and eliminating the need for costly additional circuitry.
