Code 10.4 2 I2EM Backscattering from Periodic Sinusoidal Surface 

 This module computes the backscattering coefficient, σ0, for a given periodic sinusoidal surface, with a random smaller-scale component, using the I2EM model. Various parameters of the sinusoidal rough surface can be specified, such as the dielectric constant ϵ = ϵ' -j ϵ'', the type of correlation function, the parameters of the correlation function, the parameters of the sinusoidal function, and the azimuth angle. The model is constrained to realistic surfaces with ( rms height / correlation length ) ≤ 0.25 and ( amplitude / period ) ≤ 1/20. Azimuth angle = 0 corresponds to look direction parallel to the rows.
