2014 ESR experiments have been performed on phosphorus-doped silicon with concentrations ranging from 1.9 x 1017 cm-3 to 2.8 1018 cm-3 at 1.4-4.2 K and 100 GHz. The peak shift of the central ESR line with respect to the center of the two hyperfine lines has been investigated as a function of donor concentration, temperature, and microwave power. In general, it consists of a microwave power-depe...

Virus is known to resonate in the confined-acoustic dipolar mode with microwave of the same frequency. However this effect was not considered in previous virus-microwave interaction studies and microwave-based virus epidemic prevention. Here we show that this structure-resonant energy transfer effect from microwaves to virus can be efficient enough so that airborne virus was inactivated with re...

zns  nanoparticles  were  synthesized  via  a  simple  surfactant  free microwave  route.  in  this  synthesis, thioacetamide  was  used  as sulfur  source.  the effects  of different  parameters  such  as  type of zinc precursor,  time  and  power  of  irradiation  on  the  morphology and  particle  size  of  the  products  have been  investigated.  the nanostructures  were  characterized  by ...

Development of the effective sources of ultrawideband signals is stimulated by much interest to ultrawideband communication technologies. Chaotic oscillators can play the role of such sources. In the report structure of the microwave ring oscillator capable to generate ultrawideband microwave chaotic signal with uniform power spectral density, is proposed. Its evolution from distributed element...

Evaluating the power densities emitted by GSM1800 and GSM900 BTS antennas isconducted via two methods. Measurements are carried out in half a square meter grids around twoantennas. CST Microwave STUDIO software is employed to estimate the power densities in order fordetailed antenna and tower modeling and simulation of power density. Finally, measurements obtainedfrom computational and experime...

The paper examines the modern electromagnetic software available in the market (Multiphysics by ANSYS, QuickWave-3D by QWED, EMC2000-VF by Matra Systemes & Information, Microwave Studio by CST, and some others) with respect to their applicability to the typical problems of microwave power engineering. The solutions to the especially designed benchmark problem (2.45 GHz microwave oven) obtained ...

OBJECTIVE In order to utilize fat from broiler byproducts efficiently, it is necessary to develop an appropriate rendering procedure and establish quality information for the rendered fat. A study was therefore undertaken to evaluate the influence of rendering methods on the amounts and general properties of the fat recovered from broiler skin. METHODS The yield and quality of the broiler ski...
