Abstract. A modification of the method for measuring the dielectric properties of materials in the EHF band is proposed. It is based on the application of the electromagnetic properties of plane wire grids. Using these grids, one can apply the methods based on the measurement of reflection and transmission characteristics of a dielectric plate to the study of liquid dielectric materials, as well as modify the method based on measuring the reflection coefficient of a plane dielectric plate.

Key words: dielectric properties, EHF band, wire grids, interference pattern.
