ABSTRACT
The focus of Chapter 4 was mainly based on the pair correlation function. In this chapter, Boolean models (Bms) are discussed. The basic idea of Bms is to neglect each kind of interrelation between the spatial positions of the particles. Sometimes, the Bm is called the Poissonian penetrable grain model. The connections between the set covariance C(r) and derived scattering parameters of the model are explained. The Bm is a suitable approximation for many practical applications, which has been demonstrated in several papers (see Hermann, 1991 [150] and references to other papers included therein). In this regard, the paper by Sonntag et al. (1981) [208] is remarkable.
