Design, Analysis, and Implementation of Spacecloth Based on Hexagonal Resistor Grid Network of Planar Resistors

摘要

A novel spacecloth is designed based on a hexagonal grid network of planar resistors. S-parameters of spacecloth are derived for plane wave transmission through spacecloth. A prototype C-band spacecloth is developed and tested using waveguide simulator in conjunction with vector network analyzer to validate the design. Predicted, simulated, and measurement results agree well. The spacecloth can be used for realizing ultra wide band absorption of more than 95% from 2.4 to 17.7 GHz in a four layer-Jaumann absorber.
