What is BS EN 62810- Dielectric rods- Cylindrical cavity method about?
BS EN 62810 is a safety standard on the cylindrical cavity method to measure the complex permittivity of low-loss dielectric rods.
BS EN 62810 relates to a measurement method for complex permittivity of a dielectric rod at microwave frequency. The method described in BS EN 62810 has been developed to evaluate the dielectric properties of low-loss materials in coaxial cables and electronic devices used in microwave systems.
BS EN 62810 uses the TM010 mode in a circular cylindrical cavity and presents accurate measurement results of a dielectric rod sample, where the effect of sample insertion holes are considered accurately based on the rigorous electromagnetic analysis.
In comparison with the conventional method described in IEC 60556 [2]1, the method described in BS EN 62810 has the following characteristics:
- The values of the relative permittivity ε ' and loss tangent tan d of a dielectric rod sample can be measured accurately and non-destructively
- The measurement accuracy is within 1,0 % for ε ' and within 20 % for tan d
- The effect of sample insertion holes is corrected using correction charts presented
Note: The method described in BS EN 62810 is applicable for the measurements on the following condition:
- Frequency: 1 GHz ≦f ≦10 GHz
- Relative permittivity: 1 ≦ε ' ≦100
- Loss tangent: 10–4 ≦tan d ≦10–1
