EM programmer's notebook-benchmark radar targets for the validation of computational electromagnetics programs

Efficient Meshing Scheme for Bodies of Revolution-Application to Physical Optics Prediction of Electromagnetic Scattering

“…This is due to a variety of sources such as measuring instruments or human factors. However, the geometries that are meshed and simulated in this paper are benchmark targets that are provided for the validation of computational electromagnetics programs by the Electromagnetic Code Consortium (EMCC) [24]. Furthermore, our simulation results are compared with physical optics results of FEKO which demonstrate the proper accuracy of the presented method.…”

“…The backscattering cross section for both medium and high mesh resolutions are computed in φ = 0 plane for incident angles 0 • to 180 • with angular resolution of 0.5 • at 9 GHz. The results are compared with measurement data for V V polarization [24] and physical optics simulation of FEKO in Figure 6(a). As observed, the results FEKO-PO proposed method (high mesh resolution) proposed method (medium mesh resolution) measurement [24] (a) of our proposed method yields the same accuracy as FEKO.…”

“…The procedure is repeated for a medium mesh resolution with z max = π/100 and φ max = π/50, which results in 396 patches. The backscattering cross section for both high and medium mesh resolutions is obtained and compared with measurement data [24] in Figure 5(a). V V polarization is assumed but similar results are obtained for HH polarization.…”

A Cell-Vertex Finite Volume Time Domain Method for Electromagnetic Scattering

“…The present cell-vertex based FVTD scheme is used to solve for electromagnetic scattering from various perfectly conducting 3D geometries and compute the RCS. Results are presented for a sphere and NASA almond [14] with discretizations based on O-O topology and a aircraft wing geometry [15] in O-H topology. Fig.…”

New Benchmark Radar Targets for Scattering Analysis and Electromagnetic Software Validation

“…In 1987 an initiative was made in the US, creating the Electromagnetic Code Consortium (EMCC) to consolidate RCS code development. A set of geometries to be used for validating existing codes were measured and published [7,8]. Apart from this work and other recent effort [9], there are not so many measurements aimed to perform validation and it is very typical to do it through comparisons against numerical results from other codes and for simple targets which do not show in many cases specific effects that are very interesting to be studied.…”
