Research of output characteristics of the heterodyne executed on the printed circuit board with the increased resistance to electrostatic discharges
In operation results of computer simulation of characteristics of the standard analog device - the heterodyne executed on the printed circuit board from the composite dielectric having feeble conductivity are explained. Results of simulation showed that increase in specific bulk conductivity of material of the printed circuit board to 2·10 -7 Ohm -1 -m -1 practically does not change operating characteristics of a heterodyne. The possibility of effective use of the composite poorly carrying out dielectrics in standard radio engineering devices allowing to prevent origin of electrostatic discharges is set.

Abstract—We have performed computer simulations and experimental studies of characteristics of a standard analog device—the heterodyne employing a printed circuit board (PCB) made from a composite dielectric with a controlled dark conductivity. Simulation results show that an increased conductivity of the PCB smaller than 2 × 10^−7 Ohm^−1 · m^−1 has almost no effect on the ...

Semimetal states of crystalline molecular hydrogen have been obtained at a temperature of 100 K in the pressure range from 410 to 626 GPa. To analyze the nature of conductivity, the band structure is calculated in the framework of the density functional theory using the Heyd–Scuseria–Ernzerhof hybrid exchange-correlation functional. One of the semimetal states occurs in a monoclinic ...

We calculate the electrical and thermal conductivity of a two-dimensional electron gas with strong spin-orbit coupling in which the scattering is dominated by electron-electron collisions. Despite the apparent absence of Galilean invariance in the system, the two-particle scattering does not affect the electrical conductivity above the band-crossing point where both helicity bands are filled. Below the band-crossing point ...
