Dielectric permittivity (ε) is grounded in complex physics but in simple terms it can be described as the ability of a substance to hold an electrical charge. The dielectric constant (Ka) is the ratio of the permittivity of a substance to free space. The value of Ka in air is 1 and in water Ka is approximately 80. brickleberry malloy kidnappedWebAbstract: This paper presents an accurate and low-cost method for measuring complex permittivity of various concentrations of glucose/water solutions utilizing an open-ended coaxial probe.
