The method of calculation of the temperature distribution in the dielectric material for the traveling wave microwave devices is presented. The basic equations for the temperature distribution in the direction of the electromagnetic field energy propagation with considering the dependence of the dielectric parameters of a material on the temperature changes and taking into account the heat transfer to the environment for the arbitrary design of the electrodynamic system are obtained. The results of calculation and measurements of the temperature distribution of the material in the direction of the traveling wave propagationat the electromagnetic field frequency oscillations of 2450 MHz are given. The discrepancy of calculated and measured characteristics of the temperature distribution in the material does not exceed 10%.

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 ...

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 ...

One of the promising areas of microwave
resonator systems application is the possibility of their use as
frequency-selective structures for the control of physical
quantities and monitoring of process parameters. It is possible to
determine parameters of planar dielectric materials – dielectric
permittivity and dielectric loss tangent by measuring
electrodynamic characteristics of a cylinder resonator with H011
mode. Here we present the ...
