Design, Manufacturing, and Characterization of Conical Blackbody Targets With Optimized Profile

This paper describes the design, manufacturing, and characterization of conical blackbody targets to be integrated in millimeter and submillimeter wave radiometers. In particular, we present the electromagnetic properties of the binding material Stycast 2850FT, which is suitable at cryogenic temperatures, with microwave absorbing fillers between 100 and 420 GHz. On the basis of these extensive mea...
