Three-dimensional numerical simulations of fast-to-Alfven conversion in sunspots

, 2012
The conversion of fast waves to the Alfven mode in a realistic sunspot atmosphere is studied through three-dimensional numerical simulations. An upward propagating fast acoustic wave is excited in the high-beta region of the model.

Wave Energy Conversion through Oscillating Water Columns: A Review

Journal of Marine Science and Engineering
An oscillating water column (OWC) is designed for the extraction and conversion of wave energy into usable electrical power, rather than being a standalone renewable energy source.

Resonant Absorption as Mode Conversion?

, 2010
Resonant absorption and mode conversion are both extensively studied mechanisms for wave "absorption" in solar magnetohydrodynamics (MHD). But are they really distinct? We re-examine a well-known simple resonant absorption model in a cold MHD plasma that
