適用范圍：This part of IEC 61338 describes the measurement method of dielectric properties for dielectric resonator materials at millimetre-wave frequency.This standard consists of two measurement methods: a) the dielectric rod resonator method excited by NRD-guide (Non-Radiative Dielectric waveguide) and b) the cut-off waveguide method excited by coaxial cables with small loops.a) The dielectric rod resonator method excited by NRD-guide is similar to the dielectric rod resonator method given in IEC 61338-1-3. This method has the following characteristics:- a complete and exact mathematical solution of complex permittivity is given by computer software;- the measurement error is less than 0,3 % for s' and less than 0,05 x 10-4 for tan 8;- the applicable measuring ranges of complex permittivity for this method are as follows: frequency: 30 GHz < 100 GHz;relative permittivity: 2 < e' < 30;loss factor: 10~6 < tan 8 < 10~2.b) The cut-off waveguide method excited by coaxial cables with small loops uses a dielectric plate sample placed in a circular cylinder of the TE011 mode. This method has the following characteristics:- fringe effect is corrected using the correction charts on the basis of rigorous analysis;- the measurement error is less than 0,5 % for ￡' and less than 0,05 x10-4 for tan 8;- the TCF is measured with high accuracy;- the applicable measuring ranges of dielectric properties for this method are as follows: frequency: 30 GHz < 100 GHz;relative permittivity: 2 < s' < 30;loss factor: 10~6 < tan <5 < 10~2.
