Our work focuses on the study of a simple yet complete one-dimensional reverberation chamber model presented previously. The statistical properties of the fields are introduced either by varying the width or the relative dielectric constant of a perturbing lossless layer. Our aim is to show the excellent agreement between this simple model and real RCs. The field statistics in undermoded regime is examined. An intuitive three-dimensional extension of the model is presented as a rectangular non-homogenous cavity. With the use of a suitable change of variables, we are able to find an analogous RC model which results in an homogeneously-filled cavity, with a geometrical discontinuity mainly consisting of a conducting box inside the cavity. The final result is to link the one-dimensional virtual stirrer with a real one. This process is performed provided we can calculate (even numerically) the monostatic radar cross section of the actual rotating stirrer under study. Excellent agreement with measurements were found.
