Flipping the half-illuminated region. The normalized spectrum of (a) the HIM and (b) the inverted HIM. The left and right insets are the excitation position and the steady-state mode pattern, respectively in each case. The peak frequencies are (1241.713 ± 0.033) kHz for (a) and (1241.410 ± 0.056) kHz for (b), respectively. The HIM (inverted HIM) is excited at 1242.5 kHz (1241.5 kHz). The excitation frequencies are indicated as red dashed lines. The blue dots represent the eigenmodes contributing to the HIM (inverted HIM) with the horizontal positions indicating their resonance frequencies and red horizontal bars showing their linewidths. Their vertical positions of the dots indicate the magnitude of corresponding \(|c_n|^2\). The most contributing four modes, also shown in Fig. 3b as labelled a, b, c and d, are colored in cyan. The vertical error bar indicates one-standard deviation at each sample mean.
