The dual-hollow-sphere-shaped optical microresonator is shown in Figure 1. The microcapillary (Polymicro, TSP075150) with inner and outer diameters of 76 µm and 151 µm is utilized to construct the ...

Exhaustive research on single-beam metamaterial vibration attenuation structures using local resonators exists in literature. Moreover, there are recent attempts at modelling double-layered beams with ...
