FirstAs the first volumetric target, we consider a metallic cube of dimensions a × a × a, illuminated by a normally incident, plane wave source. Similar to the metal plate case, we run a parametric sweep of [[EM.Libera]] and [[EM.Tempo]] with the cube length a defined as the sweep variable. We compute the backscatter RCS of the metallic cube as a function of k₀a (normalized length or normalized frequency as you may interpret). Figure 8 shows the backscatter RCS results computed using [[EM.Libera]] and [[EM.Tempo]] and compares them with the published measured data given by Ref. [4]. Excellent agreement is observed among all three data sets.
