emission‐enhancement materialssymmetry‐related modulationThe Purcell effect significantly improves the performance of various emission devices but is typically constrained by a narrow operational bandwidth due to inherent resonant mechanisms. This study achieves broadband acoustic Purcell effect, substantially ...
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. ...

The advancement in electromagnetic metamaterials, which commenced three decades ago, experienced a rapid transformation into acoustic and elastic systems i
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 ...
while the perfectly matched layers were imposed on the left and right radiation boundary in order to eliminate reflections. A plane wave radiation boundary condition for the incident wave was imposed on the incident boundary. The effect of loss was not taken into account in the simulations. After...
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 ...
