Lower eigenoscillations responsible for the resonance frequency response forming over the single-mode range of compound screen perforated with below cutoff holes are investigated. The general principles of symmetry are applied to classify the ones in symmetry groups and to set up the peculiarities of screen resonance response as consequence of eigenoscillation intercoupling.

Waveguide slot arrays (WSA) are widely used in ground and onboard radar-tracking, radiorelay, radionavigating systems [1–4]. There is a danger of occurrence interference maxima of the higher orders in WSA on a hollow waveguides. To avoid occurrence of these maxima, distances between radiators are reduced using different ways. One of them is the use of waveguides of the Π-shaped form [2, 3], another one consists in reduction of a waveguide width [4]. To pull together radiators within the limits of one linear array and to reduce distances between radiators in the neighboring linear arrays it is possible to use slowing down a wave in a waveguide by insertion a dielectric layer.

In the millimeter- and submillimeter-wave regions, the optical principles for microwave device design are used [1] as losses in waveguide devices are unacceptably large. The optical principles of design constrain the possibilities to create the millimeter- and submillimeter-wave region element base similar to the waveguide element base. Therefore, each quasi-optical system and all its elements are specially developed when solving this or that specific problem.

Gyrotron FU CW Series which consists of 9 gyrotrons, has been designed and constructed as high power THz radiation sources and completed operational tests successfully in the Research Center for Development of Far Infrared Region, University of Fukui (FIR FU). The gyrotron series covers wide frequency range in sub-THz to THz region. Gyrotrons included in the series can operate in continuous wave (CW) mode and the output power is ranged from several watts to several hundred watts. A few gyrotrons have been applied to ESR spectroscopy in THz region, DNP enhanced NMR spectroscopy and material processing. Some other gyrotrons will be applied soon for development of high power THz technologies, for example, X-ray detected magnetic resonance (XDMR) measurement, measurement on hyperfine structure of positronium, ESR echo experiment in sub-THz region, etc. In this manuscript, development of THz gyrotrons and their applications are presented.

The heliograph of radio decameter wavelengths started to be created and developed else in 1976 on the base of antenna system UTR-2 (Ukrainian T-shaped radio telescope). Basically, the main features of the heliograph are determined by the characteristics of UTR-2. To observe stars, Sun, planets and others within the frequency range 10 – 30 MHz, the radio telescope forms five independent pencil-shaped beams with angular width 25′ × 25′. The scanning of sky area is provided discretely in declination and hour angle. The sensitivity of heliograph is about 104 Jy (1 Jy = 10−26 W/m2/Hz). At first the radio astronomy observations by the radio telescope UTR-2 (and the heliograph too) were carried out at a few discrete frequencies. This led to difficulties in distinguishing solar burst features (for example, fine structure of the solar Type II bursts and so on) with confidence. Last time the facilities of radio telescope UTR-2 have been essentially extended due to an effective broadband telescope amplifier system and a new back-end. Now the observations are conducted by means of the DSP (digital spectrum processor) in the frequency band of 16.5 MHz divided on 4096 channels. Therefore, the basic scheme of the heliograph and its properties have been improved.

It is possible to state at this point that - Strongest influence on value of errors at use of method MUSIC is stipulated by diffuse reflection coming from short-range zone of the “glistening surface”. - In array intended for getting space samples, it is necessary to use the antennas possessing satisfactory directed properties; thus their axes should be rejected from a surface upwards on such angle to obtain maximum ratio the power of received direct target signal to diffuse reflections coming from a short-range zone.

It has been demonstrated that it is possible to reconstruct 3D video sequences using depth information. Novel framework can be realized in all formats in video sequences because it does not depend on a specific hardware usually needed in existed techniques for depth map calculations. Proposed technique is applicable in other methods of 3D perception, such as polarized lens, etc. The applications of the proposed method can be useful in areas: real time 3D remote sensing, robot navigation, or 3D medical visual demonstrations.

Here we describe the new method for measuring these properties and an experimental setup that implements this method at wavelengths of about 2 mm (frequencies from 130 to 180 GHz). These samples were investigated also at frequency of 0.6 THz with help Time Domain Spectroscopy method. The new method employs the Michelson interferometer (IM) designed on a quasi-optic square metal-dielectric waveguide of cross section 20 × 20 mm [2] (Figure1).
