Experimental and numerical evidence of intensified non-linearity at the microscale: The lipid coated acoustic bubble
A lipid coated bubble (LCB) oscillator is a very interesting non-smooth oscillator with many
important applications ranging from industry and chemistry to medicine. However, due to the
complex behavior of the coating intermixed with the nonlinear behavior of the bubble itself,
the dynamics of the LCB are not well understood. In this work, lipid coated Definity®
microbubbles (MBs) were sonicated with 25 MHz 30 cycle pulses with pressure amplitudes
between 70 and 300 kPa. Here, we report higher order subharmonics in the scattered …
