Abstract The finite element numerical models of the microbubble with and without shell are built in our study. The calculation results indicate that the frequency response of the shell-microbubble is different from that of microbubble without shell. Furthermore, the frequency response of microbubble is closely related to the relevant parameters of the shell. The thickness and the Young's modulus willinfluence the frequency response. The increase of the thickness or the Young's modulus of the shell leads to the increase of the resonance frequency and the decrease of the oscillation amplitude of the microbubble.
