Abstract: This paper illustrates numerical results of millimeter wave scattering, based on a model of flat sea-surface covered by foams. This model considers the structure of foam as coated spherical particles that are randomly distributed within a cubic domain. The cubic domain is divided into five (5) two dimensional 2D slices of foam layers. Electromagnetic wave with unit amplitude was propagated through each slice of sea-foam layer for accurate prediction of millimeter wave scattering due to the interaction between the EM wave and randomly distributed air-bubbles.
