The microwave lies the lying of quality material diagraph of giving or getting an electric shock the constant, because it has and the developing of aviation aerospace, new material and satellite Yao and microwave correspondence etc. are closely related and cause more and more concern of people, the same microwave technique also got development and application.This text introduced the basic principle that the microwave Xie flaps a chamber and microwave Xie to flap chamber basic index sign and concretely elaborated rectangle microwave the Xie flaps chamber structure and the most basic mode rectangle Xie to flap chamber mold and the field of the mold structure, and the microwave Xie flaps a tiny Rao theory of chamber and lies quality tiny Rao inside the concrete chamber and thus tidy up to lie the general theory of giving or getting an electric shock the constant diagraph namely the microwave Xie flap tiny Rao method diagraph of chamber to lie to give or get an electric shock the theory method of the constant.Express this kind of the contact type diagraph theory doesn't have to operate opposite simple, the amount of sample needed is little, calculation accuracy Gao, the application is wide, particularly suitable for low exhaust to lie quality to lie the calculation of giving or getting an electric shock the constant.

The dielectric constant measurement of microwave dielectric materials is paid more and more attentions since it is closely related to a lot of fields such as aerospace, new material development, satellite remote-sensing, and microwave communications, similarly, microwave technology is also developed and applied. This paper introduces the basic principles and basic specifications of microwave resonance cavity, specifically describes the cavity structure of rectangular microwave resonance cavity, the field structure of mode and mode in the most basic mode rectangular resonance cavity, the perturbation theory of microwave resonance cavity and the specific perturbation of intra-cavity dielectrics, so that a general theory, that is the theoretical method to use the perturbation theory for microwave resonance cavity to measure dielectric constant, is summarized. It is proved that this non-contact measuring theory features relatively simple operation, less necessary samples, high calculation accuracy, wide range of applications, is particularly suitable for calculating the dielectric constant of low-loss dielectrics.

Microwave Dielectric constant of the measurement, because of its aviation, new materials development, satellite remote sensing and microwave telecommunications and other areas closely related to the cause for more and more attention, the same microwave technology has been developed and applied . This article describes the basic principles of microwave resonant cavity microwave resonator basic indicators, specifically addressed the rectangular microwave resonant cavity, the most basic mode rectangular resonant cavity mode and the mode of the field structure, and the microwave cavity perturbation theory and concrete cavity perturbation within the media to sort out the general theory of the dielectric constant measurements of microwave cavity perturbation method of measuring dielectric constant of the theory. Show that the non-contact measurement theory is relatively simple, required less sample, high precision and wide range of applications, especially for the low-loss dielectric permittivity calculations.

Microwave medium material coefficient of dielectrical loss survey, because it has with aspects and so on aerospace, new material development, satellite remote sensing as well as microwave communication close related arouses people more and more interests, similarly the microwave technique also obtained the development and the application. This article introduced the microwave resonant cavity's basic principle, the microwave resonant cavity basic quota, elaborated the rectangular microwave resonant cavity structure specifically, the most basic pattern rectangle resonator mpde and mold's field structure, as well as microwave resonant cavity small perturbance theory and in concrete cavity medium infinitesimal disturbance, thus reorganizes the permittivity measurement the general theory is the microwave resonant cavity perturbation method survey coefficient of dielectrical loss theory method. Indicated that this kind of non-contact survey theory has the operation to be relatively simple, needs the sample quantity to be few, the computational accuracy is high, the application scope is broad, especially suits in the low loss medium coefficient of dielectrical loss computation
