Dispersion relations for both bulk and surface polaritons in a subwavelength magnetic-semiconductor structure which is placed in an external static magnetic field, applied parallel to the boundaries of the layers are studied. It has been shown that the conditions of simultaneous existence of bulk and surface polaritons in the same spectral range can be reached in the system under consideration, providing a conscious choice of the constitutive parameters and material fractions for both magnetic and semiconductor subsystems.

It was revealed experimentally that at small level of magnetic field's noise (less than 4μT/Hz0.5) the dependence of gravitropic reaction of cress roots on frequency had a fine structure. The peak that corresponded to the cyclotron frequency of Ca2+ ions for the static component of combined magnetic field that was equal to 40μT became split up into three peaks (f1 = 31/3Hz, f2 = 32.5Hz f3 = 34 Hz). The frequency f1 corresponds to Ca2+ ion (the theoretical value is 31.6 Hz), the frequency f2 corresponds to hydronium ion H3O+ (the theoretical value is 32.9 Hz), and frequency f3 relates OH- ion (the theoretical value is 35 Hz), Taking into account the influence of combined magnetic field on the hydronium ions and the Del Giudice hypothesis the main doubts about the existence of ion cyclotron resonance may be broken. Hydronium ions are unusual because they have a long free path. It was revealed that the combined magnetic field tuned for the cyclotron frequency of hydronium ion changed pH of pure water. Such changes have to lead to biological effects.

We report direct visualization of spatially localized excitations in an array of 27×27 coupled rf-SQUIDs forming a magnetic meta-surface for electromagnetic wave propagation. The technique of low-temperature Laser Scanning Microscopy (LSM) is applied to investigate contributions of individual meta-atoms to the macroscopic dc flux tuned microwave response in the high rf flux limit. The obtained LSM images of the RF current distributions across the SQUID array at zero dc flux confirms a high degree of coherence of the entire meta-surface assuming radially anisotropic nearest neighbor coupling in 2D arrays of rf-SQUIDs. We also find a rich variety of spatially clustered stable dissipative states of the rf-SQUID array due to the non-uniform penetration of magnetic flux in the direction perpendicular to the uniform external magnetic field. Our measurements show that the LSM technique is a powerful tool for spatially-resolved characterization of complicated meta-materials and may be useful for their optimization.

This paper presents synthetic aperture radar techniques for impulse ground-penetrating radar system. For test measurements, we used ultra-wide band impulse ground-penetrating radar system to collect A-scan radar data and these data was demonstrated in B-scan image. Synthetic aperture radar algorithm was applied to advance the cross-range and range resolutions.

In this paper the properties the most low-frequency asymmetric oscillation of the magnetic type H111 have been studied. Possibilities of the resonance frequency fine tuning for the H111 oscillation of the waveguide-coaxial resonator with the short-circuit plunger have been analyzed. The eigen frequencies and Q-factors of the investigated oscillation in the waveguide-coaxial resonator on the basis of the evanescent waveguide have been computed. A comparison of the characteristics of the waveguide-coaxial and the waveguide-dielectric resonators has been carried out.

In this paper, the optimization of the shielding effectiveness of double braided coaxial screens in contact is obtained using semi-empirical single braid optimization formulas. Also the effect of the mutual inductance term between the double braided screens in contact is investigated. A sample optimization has been obtained practically, on one of the standard double braided RF coaxial cable namely, RG-142.

In this paper we present an experimental method of determining losses caused by 1D gratings based on applying those gratings as output couplers of THz lazers. Firstly we experimentally determined the optimal coupling coefficient for two types of gratings: wire gratings and strip gratings on dielectric substrates. Therefore we determined the value of total losses in laser cavity for each researched grating. Comparing these results it is possible to determine the losses caused by specific grating.

The paper deals with considering a problem typical for lossy compression of remote sensing images. While compressing an image under interest by DCT-based coders which are rather efficient it is desirable to predict what CR will be attained for a given quantization step. We show that such prediction is possible and it can be done easily, quickly, and quite accurately. Moreover, prediction can be done for practically noise-free images and images corrupted by unknown type of noise with unknown characteristics. Influence of noise type and image properties is briefly studied.

Ground Penetrating Radar (GPR) operating on the basis of Stepped Frequency Continuous Wave (SFCW) is analyzed for various applications with extraction of additional information about physical properties of soil and buried objects. The phase structure is obtained from the signal phase-frequency spectrum by applying the Discrete Fourier Transform (DFT) to signals on the output of SFCW georadar quadrature phase detector. It has been shown that the phase gradient of a phase-frequency spectrum of signals reflected from underground layers and buried objects are determined by their electrical properties. Also it is represented some application of such GPR to detect and recognize some explosive hazards with applying algorithm of synthetic antenna aperture technique.
