A model and method for calculating the temperature distribution of a wide range of materials in a microwave beam-type unit taking into account the reflective walls of the chamber is supposed. The experimental and modeling characteristics of the temperature distribution over the thickness of a homogeneous dielectric material at different distances from the walls of the chamber at a frequency of 2450 MHz electromagnetic field oscillations are presented.

We investigate dark counts in SNSPD with spatial resolution, using nanostrip-patterned devices with 50 Ohm matched coplanar waveguide - tapers. We found that the dark counts originate from one or several points along the strip, which we call 'weak points'. We found that the dark counts originating from different points can have different dependence of ...

We present a study of the frequency of occurrence of quasi-periodic fluctuations (QPFs) of microwave
radiation from solar active regions at the pre-flare stage. We used correlation curves obtained with the
Nobeyama Radioheliograph (NoRH). We analyzed 529 flares of classes X, M, and C (according to the GOES
classification). In a significant number of considered events (approximately 75% ...

The dynamics of the preflare phase of microwave and ultraviolet emission for M-class X-ray flares in three active regions (ARs), two flares with coronal mass ejections (CMEs) and one flare without a CME, were considered. Extrapolation of the magnetic field in the AR corona showed that eruptive events were associated with the formation of a ...

We present a study of the spatial distribution of quasi-periodic oscillations (QPOs) of microwave emission in three solar active regions before flares. The following events are considered: SOL2011-09-06T01:50M5.3, SOL2011-09-25T02:33M4.4, and SOL2012-07-08T04:19C6.6. Daily observations on the Nobeyama Radioheliograph at a frequency of 17 GHz are used. In all three cases, pre-flare trains of the QPOs of ...

To date, observational signs that determine the ability of solar active region to cause an eruption of matter into the high layers of the solar corona (CME) are not entirely clear. This makes it difficult to understand the physical mechanism of the CME trigger. This paper presents a search for observational signs that may indicate ...

In this study, a comparative analysis was carried out on the preflare and flare conditions for six flares accompanied by coronal mass ejections (CMEs) and five events not accompanied by CMEs. All of the events occurred in the period 2011–2014. The features of the spatial dynamics of microwave emission of active regions (data from the ...

This paper addresses the high-priority goal of reducing the energy cost of heat-treating foam concrete slabs. We show that this problem is best solved using microwaves as a heat source. We discuss the main advantages of microwave curing over traditional techniques for curing foam concrete slabs, and develop a design for a microwave foam concrete ...

Multi-chip embedded PCBs were in resent years the mainstream technology of electronic packaging size reduction and at the same time providing improved performance. Ultra-small package size obviously strongly impacts the SiP module thermal behaviour. Unfortunately the complete thermal design methodology was not developed for this technology till now. In this work the problem of thermal ...
