So far the firm link between the spatial arrangement of consolidated porous ceramics and their ability to attenuated thermal radiation along its direction of propagation remains a topic of debate. This particularly true for architected ceramics obtained by additive manufacturing with regular topologies. To cope with this issue, numerical 3D geometries with different arrangement of cells (regular and irregular) will be generated in this work with an homemade software. Then, the two-point correlation functions of each architecture will be computed to precise the type of spatial correlations prevailing in the medium. The analysis of the extinction cumulative distribution function curves obtained with the Radiative Distribution Function Identification method allows us to check whether or not if the attenuated thermal radiation follows an exponential decay as it the case for Beerian media. Effect of the cell size, cell numbers and cell geometries will be discussed. Finally, preliminar practical considerations will be given for making the distinction between Berian and non Beerian 3D archirectures.
