Camera Boxes: A Set of Complex Scattering Problems to Test EM Simulations and Measurements

A set of metallic structures, each consisting of an identical hexagonal prism housing a differently-shaped internal void behind an aperture, are introduced. The structures are designed to serve as precisely-defined, easy-to-reproduce, and geometrically-extensible simulation and measurement bench-marks that exhibit the complex scattering phenomena encountered in platforms containing open cavities. Sample measurement and simulation results show that the characteristics of the fields scattered by the structures depend on whether the void supports any guided-wave modes.
