Permittivity of a material
WebThe dielectric constant formula is: Where: C = capacitance using the material as the dielectric capacitor. C 0 = capacitance using vacuum as the dielectric. ε 0 = Permittivity of free space (8.85 x 10 -12 F/m i.e. Farad per metre) A = Area of the plate/sample cross section area. T = Thickness of the sample. WebPERMITTIVITY AND MEASUREMENTS 3693 where c is the speed of light in free space (3 108m/s). After obtaining the dielectric properties, the penetration depths of electromagnetic energy into selected materials can be calculated at the required frequency.
