  MHD WAVES: REALISTIC MODELLING THROUGH VARIOUS LAYERS OF THE SOLAR ATMOSPHERE

  E. Khomenko, Instituto de Astrofisica de Canarias, khomenko@iac.es

Wave transfer energy over the solar atmosphere and couple all its layers. High resolution observations reveal that wave properties such as their dominant periods, propagation speeds and directions are intimately related to the topology and strength of the magnetic field. Rich physics emerges when considering waves in partially ionized solar plasma, since partial ionization effects provide new mechanisms for the interaction of different wave modes, and also provide efficient ways of the wave dissipation. In this talk I will discuss the recent developments in the field of modeling of waves in complex solar magnetic structures with a special emphasis on the aspects involving partial ionization in the photosphere and chromosphere of the Sun.
