Here, we use these unique properties (FP resonance modes and the enhanced refractive index) of acoustic metamaterials to control the quality factor (Q) and the effective volume (Veff) to demonstrate a new class of acoustic resonator for acoustic emitter enhancement at the subwavelength scale. ...
a, Field-emission scanning electron microscope image of the LOBAR device measured in this experiment. b, Comparison of spin resonance driven at 89.5 MHz with an RF antenna (Fig. 1b, ODMR) against the LOBAR’s transducer (ODSAR), showing clearly distinguishable peaks associated in energy ...
Furthermore, the light modulation can potentially be enhanced through the disturbance of the structural interfaces by acoustic waves, which is termed the interface effect7–9. On the other hand, carefully engineered optical modes, such as waveguide, cavity, or slow-light modes in nanostructured ...
