Dilating of frequency band of an estimation of a dispersion relative inductivity

High-accuracy apparatus for researching /spl epsiv/' and tg/spl delta/ of liquid and solid dielectrics over the range of 10-10/sup 7/ Hz and 10/sup 9/-10/sup 10/ Hz frequency was designed and operates in the authors' institute. Measurement assurance as two state special measurement standards of unit of inductivity E', initial means of measurement tg/spl delta/ and standard samples of relative inductivity (SS RI), spreading on this part of the frequency band were designed. Needs of science and production require necessity of frequency band extension up to 10/sup -3/-10/sup -5/ Hz towards infra-low frequencies and area of a very high frequency of range up to frequencies about 70-100 GHz. It is bound to occurrence of volumetric-charge polarization mechanism in the field of infra-low frequencies and to considerable value of a dispersion of relative inductivity in the range of 10/sup -1/-10/sup -3/ Hz.
