WebOct 4, 2024 · For many liquid materials and biological media, their complex permittivity varies with frequency in the P-band (100–1000 MHz). In this paper, a re-entrant coaxial cavity resonance test system with intensive multi-frequency points testing capability is designed for the P-band to realize the test of the complex permittivity of P-band materials. WebThe permittivity is often shown by a non-dimensional parameter known as relative permittivity, which is the ratio of the absolute permittivity of the material by the permittivity of the vacuum. The liquids with permittivities lower than 5 times of the permittivity of vacuum are listed in Table 1 while the liquids with the relative ...
