This article presents the simulation results of a double-gap photonic band gap resonator with striped fractal elements. In this resonator, a modified fractal “Sierpinski gasket” of three iterations was applied. Fractal elements “Sierpinski gasket” were made on a suspended dielectric substrate. The frequency spectrum of the resonator was investigated in the range from 10 to 40 GHz. The calculation of the main electrodynamic parameters of the resonator - resonant frequency, characteristic impedance, unloaded Qo factor - was made. The investigated resonator can find application in devices of the klystron type, which operate as amplifiers, generators, and frequency multipliers.

This work is devoted to the development of a miniature directional coupler with a wide passband for maritime communications equipment. Artificial transmission lines having similar characteristics with quarter-wave segments, of which the directional coupler consists, are considered. Based on the calculations, a miniature coupler was modeled. Based on the simulation results, it can be judged that a working model of the device with an area of 70% less than with a traditional design was obtained. The miniature coupler is assembled for a frequency of 0.9 GHz and has a band of 67.5%. The relevance of the development is confirmed by the increased demand for compact microwave devices.

A study of waveguide structures with magnetic walls that were based on mushroom-shaped metamaterials has been carried out. We used Ansoft HFSS to simulate waveguide filters with a forbidden frequency band. The results obtained showed that a magnetic wall made of periodic various sized unit cells can provide several forbidden frequency bands instead of only one in case of single sized elements. We also demonstrated that it is possible to control rejection bands of frequency-selective surfaces by varying the permeability of ferrite coating of the metamaterial.

This paper provides a brief description of an alternative method for the direct electrodynamics problems solving. The method is being developed for its application in subsurface radiolocation and flaw detection, primarily. One of the main features of the approach is it possible application to solving the direct problem of several bodies, boundary irregularities accounting and complex-dielectric media consideration. The basis of our approach is the principle of electrodynamic equivalence of a radiating and scattering body. This method may be used, as when considering heterogeneity, as well for the buried source detection.

In this paper, the mutual synchronization of a system of two delay-coupled oscillators with hard excitation is considered. The results of the bifurcation analysis in the case of small delay time are presented. Stability of the synchronous states to variation of different parameters is examined. The domains of synchronization on the frequency mismatch - coupling strength parameter plane are plotted.

This paper demonstrates application of nonlinear large signal scattering parameters (LSSP) to the microwave nonlinear behavioral modeling on the example of two nonlinear amplifiers cascade connection. It is shown that nonlinear LSSP provides capabilities to accurately modeling the fundamental output power, gain compression and less accurately the second harmonic output power.

The problem of electrodynamic analysis and synthesis of band-pass waveguide filters on thin resonant metal diaphragms with a complex aperture is solved. A complex aperture is a combination of complementary split ring resonators (CSRRs) and a Koch fractal. The calculation of cutoff wave numbers and the components of electromagnetic fields expressions for have been carried out by the partial regions method, taking into account the features of the electromagnetic field on metal ridges. The results of computer simulation and experimental verification for a three-cavity band pass filter on a rectangular waveguide WR-137 are presented.

The paper describes the miniaturization process of a coupler in marine communication systems implemented in a single layer. A comparison of the parameters of a conventional and compact coupler is given. The miniaturization of the coupler became possible due to the use of artificial transmission lines having a shorter length than quarter-wave segments. The area of the received coupler was 73.5% less than the area of the coupler in the traditional version.
