Benchmark targets for Computational Electromagnetics programs modeling structures with edges

This paper considers several target structures containing edges which are useful to validate computer codes developed to the purpose of detecting hidden mines and Unexploded Ordnance (UXO). In particular, we investigate the capabilities of the singular basis functions´ approach in Computational Electromagnetics for formulations based on surface integral equations. We compare the solutions obtained with several analytical/numerical methods and validate the simulations with anechoic chamber measurements performed on metallic targets.
