High-resolution computer-controlled oscillator of 2-mm wave-range intended for the low temperature dielectrometer was designed and constructed. The proposed oscillator unit may be used as free-running source as well as phase locked source being included to the frequency synthesis system. Dependence of dielectric loss vs temperature for some diamond-like materials was measured using proposed oscillator unit within frequency range 110 and 145 GHz and at temperatures within 1 and 300 K.

Studied the excitation efficiency of axially asymmetric oscillation TEM10q in an open resonator (OR) with the waveguide wave TE20. Found, that when consistent oscillations excitation in the OR took place, the latter had an angular and frequency selective spectrum. With the proper selection of geometric dimensions of the active coupling elements with the OR, one can provide a high power combining coefficient in the millimeter (mm) and submillimeter (submm) wave ranges.

Apparent discrepancy is discussed between the height profiles of atmospheric conductivity derived from Schumann resonance parameters in the Earth-ionosphere cavity and using the model of the DC global atmospheric electric circuit. The issue is resolved by creating a hybrid profile of these two profiles. Close to the ground, where the resistance of the atmosphere is largest, the properties of the DC global model exert the greatest influence, whereas in the middle atmosphere, at heights between 40 and 100 km, the full wave computations show that the AC results are the more crucial. This globally averaged hybrid profile harmonizes the AC and DC conductivity data, and it might be important for future studies.

Thermoelectric materials have attracted much attention due to their potential applications in conversion of heat into electrical power or vice versa to cool the heat-generating elements using electrical power. Tetrahedrite is copper antimony sulfosalt mineral with the formula of Cu12Sb4S13, where Cu could be partially replaced by another 3d (Mn, Ag, Al, Cr, Zn, Fe) or other (4d,5d) metal. This group of compounds is very prospective for large-scale thermoelectric applications. The compounds could be represented by common formula of the compound Cu10-xM2-xSb4-yQyS13-zTz. M=Au, Mn, Ag, Al, Cr, Zn, Fe; Q=As, Sn, Zn, Pb; Z=O, Se. The procedure of solid state reaction for tetrahedrite powder samples of various composition have been developed. The single phase tetrahedrite samples of Cu12Sb2As2S13, Cu11.8Au0.2Sb4S13, and Cu10Fe2Sb4S13 have been synthesized as proved by XRD. Characterization of their magnetic properties by VSM PPMS have been done.

An important factor when realizing image capture using electronic means (photographic or video camera), is the lighting source type present at the capture moment. If the lighting is deficient, the information present in the image is hidden for the Human Vision System (HVS), such that the color and detail characteristics introduce values with low luminance. As a solution for this lighting problem, the Multiscale-Retinex (MSR) algorithm is proposed, based on the understanding of how the HVS interprets and adapts the perception of colors. This solution can be used as a preprocessing stage to correct the lack of an adequate lighting source like the standard illuminant D65 (light source with similar characteristics to midday sunlight). The MSR algorithm increase the chromatic content of the image, this improves the objects visibility in the scene. The lack effects of lighting are minimized and its magnitude content evaluates the resulting chromaticity vector to characterize the MSR.

A novel method of dielectric sample detection has been presented. The proposed measurement setup is composed of coupled-line section sensor inserted in-between two identical Marchand baluns, which provide differential excitation to the sensor. The setup allows for measurement of dielectric samples of size as small as separation between sensor's coupled strips. The proposed sensor has been theoretically investigated and confirmed by EM simulations. Additionally, the utilized miniaturized Marchand balun has been manufactured and measured. The obtained results prove the usefulness of the presented approach.

It is well known that a spin-torque microwave detector (STMD) can be used for the determination of a frequency of an external microwave signal. We show that application of two independent STMDs connected in parallel at microwaves can substantially decrease the frequency determination error. We believe that obtained results are important for the practical development and performance optimization of microwave frequency detectors and other microwave devices based on STMD arrays.

Model of water foam was presented as same layers with different dielectric and structural characteristics. Data of experimental research of dielectric properties ε and tg δ of the water foam specimens was used for calculations in wide microwave band of 8 - 12 GHz. The reflection and transmission characteristics of electromagnetic waves from foam structures with foaming ratio of layers in range from 6 till 350 were calculated. The results show an opportunity to use water foam structures in conditions of electromagnetic influences as absorbers which are able to protect working personnel from dangerous influence of electromagnetic waves.
