The conventional approach to characterisation of the wave phenomena in metamaterials (MMs) is based upon the approximation of homogenised medium. When MMs are composed of the arrays of resonant scattering elements, with their sizes much smaller than the wavelength of the propagating electromagnetic wave, MMs can be described by the effective constitutive parameters of an equivalent continuous medium. Although a number of the homogenisation procedures have been proposed for the effective linear parameters of MM such as the effective permittivity and permeability, their physical meaning and applicability limits are still debated in the literature. In this paper, we present the results of the theoretical and experimental study of transmission spectra of electromagnetic waves propagating through a finite periodic layered structure, composed of the ferrite and semiconductor layers, which is subjected to external magnetic bias. We consider both fine-layered structure and that with the thickness of the layers being of the same order of magnitude as the length of incident electromagnetic wave. The aim of the presented work is to consider new types of waves formed in the area of transfer between photonic crystal (PC) and homogenized medium. Using results of theoretical and experimental investigations we compare the theoretical model outcomes with the real processes and define the conditions of applicability of the theory.

The study of SEDs with high time resolution was made possible due to the regular modernization of the receiving equipment on the largest decameter radio telescope UTR-2. The obtained sensitivity allowed to resolve the microstructure of lightning discharges for the first time and to estimate the intensity of bursts. In addition the dispersion delay gives us a very important criterion that let reliably separate terrestrial lightning and cosmic ones.

Composites with carbon nanomaterial fillers are of interest for developing and producing cheap and effective structures for protection different systems from electromagnetic (EM) radiation. By this radiation one means, first of all, background EM noise, emitted by cellphones, microwave ovens, computers, etc. Different shielding efficiency for different purposes is needed. For example, attenuation efficiency more than 30 dB suffices for commercial application, but for military purposes - from 80 to 100 dB is necessary.

Automated analyzers, based on six-port reflectometers (SPR), are widely used for measuring the parameters of the microwave devices. In the measurement transducer of SPR the matched multiport passive microwave connection is used for the complex composition of the reference wave generator and the wave reflected from the object. In this case the parameters of the measurement system are found by preliminary calibration using at least four standards of the complex reflection coefficient (RC).

In the terahertz range of frequencies (from 0.1 to 10 THz) gas lasers are among the most common and available generators. However, the structural complexity and the complexity of service is a significant drawback of these lasers. Highly qualified personnel, is required even for the maintenance of gas-discharge lasers, which are relatively simple. Adjustment of the resonator mirrors - this is one of the most critical and complex operations that have to perform at service of such lasers. Development of laser resonators that do not require adjustment of the mirrors is an important task.

Use of photonic crystals (PhC) to localize electromagnetic field in sub-wavelength-dimensions due to the existence of the photonic bandgap (PBG) has gained tremendous interest from the research community in recent years. Localized modes within the PBG can be generated if periodicity of a perfect crystal is broken. Investigation in fields of nano-electronics, plasmonics and photonics has for an object to achieve dense integration of signal-processing components into a small volume. Most work so far has utilized planar two-dimensional (2D) structures because of ease in their fabrication. However, in this case connection with other optical components is limited to be in the plane of the structures. 3D PhCs are promising platforms for controlling radiation by means of their complete photonic bandgaps (PBGs) that will add a freedom for configuring photonic circuits in the third dimension. PhCs would play a significant role in construction of integrated optical circuit for THz generation, propagation, manipulation and measurement because of their transparency as well as low loss and dispersion in THz frequency band.

Estimates of parameters (as functions of spatial coordinates) of researched environments on their own radio thermal radiation can be received in the various ways. Systems of aperture synthesis [1, 2], mobile [2] or scanning [2-4] radiometers are being applied for this purpose. Realization of the last is interfaced to difficulties which appear in wide class of radiometric systems. The estimation of parameters significantly depends on unstability of predetection section of the receiver. These unstability are caused, mainly, by temperature fluctuations of predetection section during work of the receiver. It is possible to reduce their influence using the thermal stabilization of entrance section. But such protection increases weight and dimensional characteristics of radiometers. Refusal of thermal stabilization will demand frequent calibration of system that isn't always useful during measurements. The solution can be found use of the modulation scheme in entrance section. Authors solved problems of statistical synthesis algorithms of signal processing in modulation radiometers [5, 6]. However application of these algorithms in the scanning radiometer will be non-optimal. The solution of the problem of statistical synthesis scanning radiometer of modulation type is the actual problem considered in the report.
