Detailed design and RF analysis of a scatterometer for accurate material characterization in the 50 to 750 GHz range

Abstract

This paper describes the detailed electromagnetic modelling and design of a scatterometer to be used at the European Space Agency, for characterization in transmission and reflection of smooth as well as rough materials in the 50-750 GHz region. The scatterometer is analysed with the software GRASP. The initial design based on quasi-optics showed pour performances and was thus modified significantly, obtaining improvements in beam quality, beam displacement and cross-polar performance.
