Fig. 13. (a) Temperature dependency _w(T) of the permittivity of pure water (_d = 0) measured with the VNA dielectric sensor (solid dots) and derived from the capacitance sensor readings (hollow circles). (b) Temperature dependencies _d(T) and _dw98(T) of pure dioxane (_d = 1, hollow squares) and a solution with _d = 0.98 (hollow diamonds) deduced from the capacitance sensor readings.
