The millimeter-wave radiometric detection and imaging system currently find wide application in diverse security setups intended for disclosure of dangerous objects concealed under persons' clothing. Electromagnetic waves of this range are quite safe at modest intensities, penetrate many common barrier materials and short enough to give adequate spatial resolution for imaging of concealed objects. Among the incontestable advantages of passive radiometric systems are absolute harmlessness and ability of operation without revealing themselves. However a passive imaging system in principle suffers from lack of sensitivity for detection of weapons covered with several layers of textiles.

In recent years, the infrared and microwave properties of opal matrices have been intensively studied [1]. 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.

The paper presents the results of upgrading and description a two-wavelength “unambiguous” microwave interferometer for line integrated electron density measurements at the “COMPASS” tokamak. 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.

Sources of electromagnetic radiation in THz range with high enough power and wide frequency range are necessary for an increasing number of applications in the technologies and many scientific researches including high data rate communications, remote high resolution imaging, chemical spectroscopy, materials research, deep space research and communications, biomedical diagnostics, radar and remote sensing system, diagnostics of plasma, concealed weapon or threat detection and etc.However, at present a lot of customers are unable to use the advantages of the THz wave applications because of the absence of compact, easy in service sources. 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.

We solve the problem of surface electromagnetic waves (SEW) propagation in layered periodic structures, which contain layers with excitons, near the exciton bands in the terahertz wavelength range. The dispersion properties of electromagnetic waves for infinite and for bounded periodic structures are considered. We study the possibility of existence of SEW that can propagate along the surfaces of the bounded periodic pattern in areas forbidden for the propagation of electromagnetic waves. With the help of complex Poynting theorem it is shown that the considered SEW can exist independently or simultaneously on each surface of the structure. Obtained results make it possible to analyze the features of the surface, attached to a periodic pattern. This allows studying the quality of thin films on solid surfaces, the surfaces of biological materials, etc.

Electromagnetic wave diffraction on a crack-type defect is a typical simplest problem in the theory of nondestructive testing. Such a defect can be considered as a thin dielectric scatterer. In the scalar case of a wave diffraction problem we use the term “thin scatterer” to mean cylindrical shell when its largest thickness is much less than the length along the guide. The last one is assumed to be comparable with the excitation wavelength. In this paper we consider three mathematical models of the mentioned diffraction problem. One of them is based, in fact, on the volume integral equations approach

Short metal ridges in a rectangular waveguide appeared to be promising units for different microwave filters providing complicated frequency response. 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.

At high resolution in range and angular coordinates, there are significant deviations of distributions of fluctuations reflected by underlying surfaces and “clear” sky signals from standard [1,2]. It is caused by sequential and separate observation of surface regions with different statistical properties of the irregularities which lead to unsteadiness and non-Gaussian scattering signal. For the sea surface are areas in which there are crests of the waves, which have high reflectivity. In this report for the first time discussed the use of statistics to describe the reflected signal sea finite atomic functions Kravchenko-Rvacheva.
