Increasing the Material Diversity in the Austin RCS Benchmark Suite Using Thin Plates

A set of thin-plate problems are added to the Austin RCS Benchmark Suite to increase material diversity. These consist of problem sets II-B/C/D/E/F that involve thin perfect-electrically conducting (PEC), dielectric, magnetic radar absorbing material (MagRAM), MagRAM-coated PEC, and MagRAM-coated dielectric plates. To provide reference RCS data that enable validation, uncertainty quantification, and benchmarking, sample plates were built and a simulation-supported measurement campaign was conducted in a compact range. The measured material properties of the dielectric and MagRAM are reported; the RCS measurement setup, data collection, and post processing are detailed; and the uncertainty in measured data is quantified.
