Relative permittivity of materials
WebApr 9, 2024 · A sensor is proposed to characterize the complex permittivity of dielectric materials in a non-destructive and non-invasive way. The proposed sensor is based on a rectangular patch microstrip two-port circuit with a complementary split-ring resonator (CSRR) element. The slotted CSRR element of the sensor plays a key role in determining … Webpermittivity (electric permittivity): Permittivity, also called electric permittivity, is a constant of proportionality that exists between electric displacement and electric field intensity. This constant is equal to approximately 8.85 x 10 -12 farad per meter (F/m) in free space (a vacuum). In other materials it can be much different, often ...
