BS EN 62562:2011

What is BS EN 62562- Cavity resonator method about? 

BS EN 62562 is an international standard that focuses on the techniques to measure the complex permittivity of low-loss dielectric plates. 

BS EN 62562 describes a measurement method of dielectric properties in the planar direction of the dielectric plate at microwave frequency. The method described in BS EN 62562 is called a cavity resonator method.  

BS EN 62562 has been created to develop new materials and to design microwave active and passive devices for which standardization of measurement methods of material properties is increasingly important.  

BS EN 62562 is applicable for the measurements on the following condition: 

• Frequency: 2 GHz < f < 40 GHz 
• Relative permittivity: 2 < ε ' < 100 
• Loss tangent: 10–6 < tanδ < 10-2
