Summary
This standard specifies the measurement method for the dielectric properties of dielectric resonator materials in the millimeter wave frequency band. This standard contains two measurement methods: the dielectric cylindrical resonator method excited by a non-radiating dielectric waveguide (NRD waveguide) and the cut-off waveguide method with small circular ring coaxial cable excitation.
