Possibility of unambiguous simultaneous assessment of range and speed using pulse millimeter wave radar. It is shown that for high-speed targets it is impossible to measure speed and distance simultaneously using coherent pulse packet as well as use of wobble of repletion frequency. Therefore the use of radio pulses with high repetition frequency and stochastic frequency modulation is proposed and their properties are studied.

We address surface and volume resonance in two concentric cylindrical graphene shells driven by the H-polarized plane wave of the THz range. Modeling implies analytical solution of the wave scattering in presence of impedance boundary conditions at thin graphene shells. Cases are considered of graphene positioned in the free space and at the inner and outer sides of a dielectric tube. Spectra of normalized scatter and absorption cross-sections are presented together with the spatial distributions of the field in the vicinity of object. These reveal hybrid resonance of surface plasmons and the eigen-waves in separating dielectric tube.

Melanoma is a disease with elevated rates of apparition in the world and the dermoscopy procedures help the physicians to get a correct diagnose of this disease. In this paper, we propose a system CADe to extract features of such type of images, based on designed algorithm that uses ABCD Rule and Textural Features to get a final classification via Support Vector Machine.

Microwave ray trajectories are calculated in the geometrical optics approximation. The calculation results prove a possibility of using experimentally the methods of mutlicomponent gas-metal plasma diagnostics based on the microwave refraction in plasma. In the experiments the scattering of microwaves at an angle of approximately sixty degrees was observed. Spectral analysis of transmitted and scattered signals was performed.

Scattering of surface TM polarized plasmon-polariton waves by a finite strip of the flat metal-vacuum interface with randomly fluctuating impedance is studied. We analyze the integral equation governing the scattering of the incident surface plasmon-polaritons, which is valid for arbitrary scattering intensity and arbitrary dissipation in the conductive medium. The strength of the scattering is shown to be controlled not only by the parameters of the fluctuating impedance (dispersion, correlation radius, the length of inhomogeneity region) but also crucially depends on the conductivity of the metal. If the scattering operator norm is small as compared to unity (weak scattering limit), the incident surface plasmon-polariton is mainly scattered into the vacuum, thus losing its energy for excitation of non-isotropic bulk quasi-Norton waves. Under condition of strong scattering, the radiation of waves into the free space is highly suppressed, and the incoming surface plasmon-polariton is almost ideally backward-reflected from the inhomogeneous part of the interface.

Coupled first-order differential equations are obtained for the field amplitudes of a single wave in cylindrical weakly irregular waveguide with anisotropic impedance surface. The equations are valid for both types of hybrid waves. For closed uniform cavity with ideal side walls, they yield analytical solution to eigenvalue problem. For open gyrotron cavity, they reduce to known form as impedance approaches zero. Gyrotron cavity with anisotropic wall impedance of special form is considered as numerical example.

New simulation technique of a 2D periodic structure excitation by an electromagnetic wave incident an arbitrary angle is suggested. The approach is based on the statement that all pulsed fields arising in the reflection and transmission areas of a periodic structure are unambiguously determined by their own longitudinal components. We use ordinary Yee grid that allows us to implement computer simulation of an incident wave with FDTD algorithm.

The results of both gyrotron output power and frequency stabilization by double PID feedback control of acceleration voltage and anode voltage have been presented. The second harmonic 460 GHz Gyrotron with isolated collector has been used in the stabilization experiment. In the long term experiment, the frequency stabilization was better than 10-6 and the power stabilization was better than ±1%.
