For positive frequencies, this spectrum is confined to the interval (2ωc −2W,2ωc +2W). • The spectra for these two terms must not overlap. This requirement is met if 2W < 2ωc − ...

As expected, higher harmonics caused by the nonlinear behavior of the microbubbles are visible. A significant observation is that for j = 1, there is a dip in the fundamental and the higher harmonics are relatively strong, whereas for j = 14 orders, the fundamental is partly …
