25、 materials at millimetre-wave frequency FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international co-operation on all que
26、stions concerning standardization in the electrical and electronic fields. To this end and in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “ IEC Publicati
27、on(s)” ). Their preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with may participate in this preparatory work. International, governmental and non- governmental organizations liaising with the IEC also participate in this preparation. IEC
28、collaborates closely with the International Organization for Standardization (ISO) in accordance with conditions determined by agreement between the two organizations. 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international consensus of opin
29、ion on the relevant subjects since each technical committee has representation from all interested IEC National Committees. 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National Committees in that sense. While all reasonable efforts are made to e
30、nsure that the technical content of IEC Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any misinterpretation by any end user. 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications transparently
31、 to the maximum extent possible in their national and regional publications. Any divergence between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter. 5) IEC provides no marking procedure to indicate its approval and cannot be rendere
32、d responsible for any equipment declared to be in conformity with an IEC Publication. 6) All users should ensure that they have the latest edition of this publication. 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and members of its
33、technical committees and IEC National Committees for any personal injury, property damage or other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other
34、 IEC Publications. 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is indispensable for the correct application of this publication. 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the s
35、ubject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights.

IEC:2005(E) WAVEGUIDE TYPE DIELECTRIC RESONATORS Part 1-4: General information and test conditions Measurement method of complex relative permittivity for dielectric resonator materials at millimetre-wave frequency 1 Scope and object This part of IEC 61338 describes the
43、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
44、 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 com
45、puter software; the measurement error is less than 0,3 % for? and less than 0,05?104 for tan?; the applicable measuring ranges of complex permittivity for this method are as follows: frequency:30 GHz 5. Table 2 shows the example of dimensions for dielectric strips of NRD-guide in Figure 2b. Dielectr
46、ic strips of the NRD-guide are made of PTFE or cross-linked styrene copolymer. Figure 3 shows a waveguide transducer that connects the measuring apparatus to the measurement equipment with WR-15 or WR-10 waveguides. Table 3 shows the dimensions of the waveguide transducers. As shown in Figure 2b, th
47、e end of the dielectric strip of the NRD- guide is sharpened in the transducer.
