(color online) Contour plots of wave energy density (in units of J/m3) (a) and power deposition density (in units of W/m3) (b) for three typical frequencies: 120 kHz, 170 kHz, 220 kHz. The left figure is identical to Fig. 16 in the previous study.[5] The white bar labels the axial location of antenna.
