METHOD FOR MEASURING REFLECTIVITY OF REFLECTOR MATERIAL Russian patent published in 2021 - IPC G01R27/06 

FIELD: physics.

SUBSTANCE: invention relates to the super-high frequency (SHF) technology and can be used for reflectivity control of reflective materials during the manufacture process, for example, in materials used for manufacture of space antenna reflectors. The essence of the method: the reference and the measured samples are alternately installed onto the side wall of the wave guide. The transmission coefficients are measured, and the reflectivity of the material sample is determined as

wherein G_meas, G_ref are the reflectivities of the measured and reference samples, K_{trans meas} and K_{trans ref} are the measured transmission coefficients thereof.

EFFECT: simplification of apparatuses implementing the measurement method and reduction of their dimensions.
