Course Contents
Basic principles of radiation of (dilatational) acoustic waves are derived. Integral representations and integral equations for the scattered wavefields are discussed. The scattered wavefields are analysed, using the first Born approximation. The acoustic reciprocity theorem and its possible applications are briefly discussed. The basic principles of radiation of dilatational and shear elastodynamic waves are developed. Integral representations for the radiated wavefield of an arbitrary source are derived. The Rayleigh-Betti reciprocity theorem and its applications are briefly discussed.
Study Goals
1. Knowing how to derive the macroscopic basic acoustic and elastodynamic equations from the underlying physical conservation laws.
2. Knowing how to employ integral transformations for the solution of the basic acoustic equations.
3. Knowing how to derive the point source solution (Green's function) in an unbounded medium.
4. Knowing how to solve specific problems using the reciprocity theorem.
5. Knowing how to formulate and solve the scattering problem.
