Large Load Bearing and Low Scattering Foam Holder Design

For the testing requirements of electromagnetic characteristics of large outdoor equipment, the researchers designed a set of a large foam holder with foam pin connections between layers in a round table shape. For the testing requirements of electromagnetic characteristics of large outdoor equipment, the researchers designed a set of a large foam holder with foam pin connections between layers in a round table shape. The electromagnetic simulation analysis shows that the RCS value of the foam holder can be reduced to below -20dBsm in the frequency range of 300MHz∼40GHz by optimizing the diameter of the bottom surface of the circular table. The mechanical simulation analysis shows that the foam pin connection between the layers of the foam bracket can greatly improve the wind resistance of the bracket and its safety when subjected to ambient extreme wind loads under both no-load and full-load conditions.
