FINAL TECHNICAL REPORT THEORETICAL STUDY OF MAGNETO-HYDRODYNAMIC, MAGNETO-ACOUSTIC, AND MAGNETO ELASTIC PHENOMENA

摘要

This report brings together in a coordinated fashion the most important results obtained during the three years of our research proj-ect. According to the original Research Proposal, we had agreed to devote our efforts to the systematic study of the soluble unbounded media and boundary value problems in the fields of magneto-acoustics, magneto-elastic waves, and magneto-hydrodynamics.nThe underlying theory and the results obtained in our studies have been presented in five technical notes which are listed at the end of this report, and in which we have made a systematic study of plane homogeneous waves and cylindrical waves in a homogeneous and isotropic medium. We have examined in detail the modes of propaga?tion in (1) an ideal incompressible fluid (Alfven waves); (2) an ideal compressible fluid subject to adiabatic processes (magneto-acoustics);
