Webmaterials. Thus, dielectric constant is typically the primary component of dielectric permittivity. Magnetic permeabil-ity, the magnetic field divided by the magnetic field strength, is the product of the permeability of free space (m 0) and relative magnetic permeability ( m r). The effect of magnetic permeability on GPR response is negligible for WebIn this range dielectric constant measurement using the reflection coefficient will be more sensitive and hence precise. Conversely, for high dielectric constants (for example …
