Fig. 6: Coupled bound states in the continuum (BICs) - amplitude spectral density (ASD) of voltage signal.
From: Exceptional energy harvesting from coupled bound states
a Single fully reduced cavity (FRC) (solid blue line) and paired FRCs (dashed orange line). b Coupled BICs. The ASD of the output voltage of the first cavity is marked by the dashed orange line. The ASD of the output voltage of the second cavity is marked by the solid blue line.
