The surface of the reflector is discretized using a triangular surface mesh generator with a mesh density of 10 cells per wavelength along each linear direction. On the average, this creates about 230 cells per square wavelength. In the case of the above parabolic reflector, a total of 50,342 triangular cells are generatedas shown in the figure below. <table><tr><td>[[Image:ART PARAB Fig2A.png|thumb|left|640px| The triangular surface mesh of the parabolic reflector created by EM.Illumina's mesh generator.]]</td></tr></table>Â [[EM.Illumina]]' IPO solver is highly parallelized for multi-core CPU architectures. The IPO simulation was performed on an ASUS laptop computer with an Intel i7-4860 HQ processor with eight cores. The laptop features 32GB RAM memory. The entire simulation takes 254 seconds. This includes the two IPO iterations and computation of the full 3D far-field radiation pattern at angular resolution of 1° along both azimuth and elevation. The figures below show the surface electric current distribution on the parabolic reflector and its 3D radiation pattern. The computed directivity is 27.9dB, which agrees very well with the estimated analytical value.
