ABSTRACT
General principles of electromagnetic wave scattering are sum-
marized, with emphasis laid on small-angle X-ray scattering. The
conventional analysis of scattering data is based on the various ways
of plotting the data according to the simple model approximation. In
order to avoid the artifact due to the simple model approximation,
the analysis of the scattering data is performed by either adapting
a triaxial model of homogeneous density distribution, a molecular
model, or a density distribution function.
