Investigation of the immunity of computer equipment to the power-line electromagnetic interference

Abstract: An experimental setup for investigating the immunity of computer equipment to the power-line electromagnetic interference has been developed. The results of quantitative investigations of the performance of the computer equipment subjected to the action of nanosecond and microsecond electromagnetic pulses propagated through the power line as well as the results of investigations of the efficiency of external devices for protecting the computer equipment from the action of electromagnetic pulses propagated through the power line are presented.

Magnetic induction tomography

Abstract: The principles underlying the operation of the magnetic-induction tomograph are examined. The possibility is shown to exist of independently reconstructing the distributions of conductivity and permittivity inside an object as it is explored by an alternating magnetic field. Some of the likely configurations for the measuring system of a magnetic-induction tomograph, an image reconstruction algorithm, and applications of magnetic-induction tomography are discussed.

Electronic devices with virtual cathodes (review)

Abstract: A review of the modern state of the physics, technology, and application of electronic devices with virtual cathodes is presented. Their application as high-power microwave generators and amplifiers, as components of high-current switching equipment, in the technology of collective acceleration of positive ions and electrons, generation of intense pulses of soft X rays, and in ultrahigh-vacuum measurements is considered. New circuit designs are presented, and the recently obtained experimental data are analyzed.

A modification of the method of discrete sources based on prior information about the singularities of the diffracted field

Abstract: A simple and universal method for constructing the auxiliary contour in the procedure of the method of discrete sources is proposed. The method analytically transforms the initial contour using a natural analytical extension of the diffracted field. The resultant algorithm generates a well posed small-size system of linear equations. The accuracy of the solution substantially improves with increasing the number of equations. This approach is shown to have significant advantages over the traditional technique for constructing the auxiliary contour.

Metamaterials with extreme material parameters

Abstract: Metamaterials are characterized by their nonconventional material parameters, examples being media that possess very large or very small, even negative, permittivities and permeabilities. This article discusses a classification scheme in which various electromagnetic materials with extreme values of parameters (very large or very small) can be placed and related to one another.
