Query: Mathematical modelization of the Photoacoustic effect generated by the
  heating of metallic nanoparticles   This paper is devoted to the modelization of the photoacoustic effect
generated by the electromagnetic heating of metallic nanoparticles embedded in
a biological tissue. We first derive an asymptotic models for the plasmonic
resonances and the electromagnetic fields. We then describe the acoustic
generation created by the electromagnetic heating of the nanoparticle.
Precisely, we derive the model equations that describes the coupling between
the temperature rise in the medium and the acoustic wave generation. We obtain
a direct relation between the acoustic waves and the electromagnetic external
sources. Finally, we solve the multiwave inverse problem that consists in the
recovery of the electric permittivity of the biological tissue from the
measurements of the generated acoustic waves on the boundary of the sample.
