It is thought that the opal matrices containing nanoparticles of magnetic materials in the intersphere voids may form a most promising class of materials used in centimeter- and millimeter-wave devices [2, 3]. Nickel-zinc, cobalt-zinc, and other ferrites seem to be proper materials for the filling owing to a lucky combination of such properties as high resistivity, low dielectric loss, high Curie temperature, and chemical stability. Application of microwave methods seems to be effective since these methods enables to estimate the dynamical and relaxation parameters of materials. Microwave properties of opal matrices containing the nanoparticles of different ferrite-spinels in the inter-sphere voids are discussed in this work. Microwave properties are measured at frequencies of millimeter waveband. Variations of a microwave signal passed through the magnetic nanocomposite occur mainly due to variations of the surface impedance under magnetic resonance condition and due to absorption of the wave. At higher frequencies the antiresonance is possible in fields lower than the resonance field. The antiresonance manifests itself as a maximum of transmission and/or reflection coefficients.","PeriodicalId":104362,"journal":{"name":"2013 International Kharkov Symposium on Physics and Engineering of Microwaves, Millimeter and Submillimeter Waves","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124259478","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The probing signals in the frequency range of 131 and 133 GHz are generated by IMPATT diode oscillators. Double conversion heterodyne receivers are used for detection. Use of each oscillator is twofold: as a source for the probing signals and as a local oscillator for heterodyne detection. The plasma is probed with two separate waves of different wavelengths traveling along identical paths to meet each other. Each probing beam experiences a different phase shift φ1 and φ2 and the “unambiguous” interferometer determines the difference φ1-φ2. The phase measurement is realized by using the 3 pieces of phase detectors based on pairs of phase/gain evaluation boards (AD8302). Application of the phase detectors provides information on the average plasma concentration in real time and restore the values of plasma density in the case of phase jumps by an amount > 2π.","PeriodicalId":104362,"journal":{"name":"2013 International Kharkov Symposium on Physics and Engineering of Microwaves, Millimeter and Submillimeter Waves","volume":"35 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126172203","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Existing gyrotrons are powerful devices but they are huge, expensive and difficult in operation complexes. Another and main technical disadvantage of gyrotrons is narrow frequency range. At the same time both solid state devices and BWOs have low level of output power that is not enough for many applications.In this work the description of developed BWO-Clinotrons of millimeter and sub-millimeter ranges is presented. Experimental results on both formation and transportation of intense electron beam interacting with the space harmonics of slowing wave system show the possibility to increase the output power of THz clinotrons. Second part of this work is dedicated to development of low-voltage CRM which can be used in mentioned applications.","PeriodicalId":104362,"journal":{"name":"2013 International Kharkov Symposium on Physics and Engineering of Microwaves, Millimeter and Submillimeter Waves","volume":"21 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115017010","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In particular, a waveguide containing two rectangular even (or uneven) ridges was used [1] to provide high-quality resonant reflection of the incident mode. A pair of equal height posts in a rectangular waveguide was used lately [2] in order to design a bandpass filter generating an improved response with additional attenuation poles. A quasi-elliptic filter based on a pair equal height posts was reported recently [3]. Off-centered single post and slant single ridge were used successfully in a modern filter design as well [4, 5]. Nevertheless the physical nature of the phenomenon of an attenuation pole generation provided by all the mentioned resonant sections remained unrevealed. Here we use the spectral theory of open waveguide resonators [6-8] to solve this problem. Within the frames of the spectral theory a waveguide unit is considered as open waveguide resonator loaded by semi-infinite guides. Different resonant regimes are interpreted as a response on the excitation of the natural oscillations of the resonator. Similarly to [9], we expect that understanding the physical nature of the resonant phenomena makes their conditions and limitations more clear.","PeriodicalId":104362,"journal":{"name":"2013 International Kharkov Symposium on Physics and Engineering of Microwaves, Millimeter and Submillimeter Waves","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2013-06-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128962211","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
