Microwave emission of foam with Kelvin´s structure based on fast solutions of wave equations

The foam covered ocean surface is treated as densely packed air bubbles coated with thin layers of seawater. A more realistic structure, Lord Kelvin´s tetrakaidecahedron with close to minimal contact surface area, is considered. We calculate the absorption coefficient at from 1.5 GHz to 36.5 GHz by using UV multilevel partitioning method (UV-MLP) to solve Maxwell´s equations. Results of absorption coefficient for scalar waves are illustrated.
