In this work we show some numerical aspects related to the full-wave 3D simulations of absorber wall properties. Two problems are discussed: (i) characterization of the dielectric properties of the absorber medium and (ii) modelling of the absorber wall geometry terminating the EMC facility. It is shown that approximation of the constitutive properties of the absorber medium by Debye models with several relaxation terms can lead to a better accuracy than for a single term based Debye formula description. Regarding absorber wall geometry: multilayer models characterized by anisotropic permittivity distribution offer better approximation properties than isotropic multilayer models.
