Abstract
Two critical properties of stationary random fields are their degree of smoothness and the rate of decay of correlation at long lags. These properties are in turn closely connected to the behaviour of the random fields’ spectral densities at infinity and at the origin, respectively. Many standard models have flexibility at one but not both of these scales. Recent works have proposed a number of models with at least some flexibility at both scales. This chapter summarizes some of these proposed models and analyzes their local and global behaviour, both in terms of their covariance functions and the associated spectra. Some ways to obtain models allowing greater flexibility are described.
