WebApr 9, 2024 · The permittivity of (glass) varies from 5 to 10, depending on its chemical composition; however, in microwave circuits, the value 5.5 is usually used [ 3 ]. Figure 8. Transmission coefficient (S 21) simulated results as a function of the resonance frequency of the sensor for different MUTs. WebThis gives a value of free space permittivity which in practice is often used in the form These expressions contain the units F for Farad, the unit of capacitance, and C for Coulomb, the unit of electric charge. In the presence of polarizable or magnetic media, the effective constants will have different values.
