Analysis of the energy transfer process for multiple scattering problems involving lossy media
Andreas Kalogeropoulos,
Nikolaos L. Tsitsas
Abstract:The energy transfer process for acoustic propagation and scattering in inhomogeneous, lossy media is rigorously investigated. Two problems are considered: an arbitrarily composed cluster of lossy scatterers, excited by a single point source and a layered, lossy medium excited by an internal point-source distribution. Energy conservation laws and optical theorems are established. The connection of active intensity with the scattering cross section and the relation between reactive intensity and Lagrangian densi… Show more
