Abstract :
The moderate-incidence microwave backscattering from two-dimensional (2D) profiles derived from the measured upwave-downwave cross-sections of the crests of spilling breaker water waves is considered using a computational EM approach. In particular, anomalous polarization ratios occurring both while the wave is steep prior to breaking and when it is covered with distributed-surface roughness after breaking are considered.
