[DOI: 10.21982/M8BC7Z] I2EM Backscattering from Single-Scale Random Surface
Fung, Adrian
This module computes the backscattering coefficient, σ⁰, for a given random rough surface, using the I²EM model. Various parameters of the rough surface can be specified, such as the dielectric constant ϵ = ϵ' -j ϵ'', the type of correlation function, and the parameters of the correlation function. The model is constrained to realistic surfaces with (rms height / correlation length) ≤ 0.25. ks is also constrained to be less than 1.
