The usage of graded-gap semiconductors can increase the efficiency and output power of Gunn generators. The energy gap between the valleys in InBN and GaBN compounds, unlike other ternary semiconductor nitrides, can be reduced to zero. This gives the opportunity to find the optimal distribution of the BN component in graded gap compounds for Gunn diodes. In this paper we present the results of numerical experiments on the oscillation generation in the range from 300 to 700 GHz using the n+-n-n+ Gunn diodes based on InBN and GaBN graded gap semiconductor compounds at different BN distribution. We have estimated the cutoff frequency of mentioned diodes. For the efficiency we have found out that at optimal BN distribution graded-gap semiconductor InBN and GaBN Gunn diodes exceed GaN and InN diodes in more than two times. We also have found out that power consumption of graded-gap InBN and GaBN diodes is 11÷19% less the power consumption of InN and GaN diodes.

The report presents the results of the design and description of the two frequencies heterodyne millimeter wave interferometer for measuring the linear integral electron density in the tokamak “COMPASS”. Microwave part of the interferometer based on solid-state transceivers with a phase locked loop. The interferometer consists of two solid-state transmitters and two millimeter wave receivers operating on 139,6GHz and 138,9GHz. Signals of oscillators and heterodyne receivers are synchronized by phase-locked loop system. The phase measurement is performed using a three-channel phase meter, based on programmable logic arrays (PLA). The interferometer provides information on the average electron density in plasma in real time and is used in the plasma discharge control system.

The authors present the preliminary results on simulation and experimental study of K-band HTS (high-Tc superconductor)-based microstrip quasi-optic resonator. The resonator is the developing result of the proposed earlier microstrip quasi-optic resonator based on normal metal disk on dielectric substrate. The applied aspects of HTS quasi-optic resonator are discussed briefly.

Analysis of the electrodynamical properties of the infinite periodical grating without one strip is performed in this paper. The H-polarization case is considered. The mathematical model is based on the singular integral equations method. Scattered field is presented as sum of three summands: field of the infinite periodical grating, field of a single strip of the infinite periodical grating and correction field. The directional patterns and field distribution are represented.

In order to estimate radar detectability for some complex shape target one need RCS for this target. For complex object RCS has different values for different incident wave direction. So object detectability estimation can be provided with the help of statistical processing RCS values for different incident angles (BSP). In this paper we discuss which step should be choosing for BSP calculations or measurements.

The detection of explosives and illicit substances is a very important problem nowadays. Especially, improvised explosive devices (IEDs) manufactured from homemade explosive materials has become an issue of growing importance. In this work, recent developments in the field of time domain (TD) NMR and microwave/sub-THz detection of liquid substances are reviewed. It has been shown that both TD NMR and MW dielectric spectroscopy are potentially very effective techniques to detect content of concealed liquids.

The possibility of the frequency stabilizing of mm-wave oscillator by external high-Q shielded dielectric resonator through their electromagnetic coupling at using the planar waveguide is considered. It is shown that the phase synchronization of the waves emitted by the oscillator and the own whispering gallery modes of shielded resonator is achieved by changing the position of the output slot of the oscillator in a planar waveguide. Thus, oscillator frequency stabilization by the external high-Q resonator is achieved on a “to pass” scheme. The high efficiency coupling between shielded resonator and planar waveguide is shown.
