## Wave diffraction by a stripline array with passive loads

The algorithm of estimating the density of surface magnetic current induced on the array aperture has been obtained as a result of the rigorous solution of the problem of plane wave diffraction on a double periodic array of stripline elements of any shape with passive loads. Electromagnetic wave diffraction

## Electrodynamics of substances with simultaneously negative electrical and magnetic permeabilities

... materials, such as magnetic metals or magnetic semiconductors, having simultaneously negative electrical and magnetic permeabilities are considered. One finds that the refractive index with respect to vacuum is negative; that the Poynting vector and the wave vector of propagating EM waves have opposite signs; that the sign of the Doppler effect is opposite that, for ordinary materials and that the Cherenkov radiation cone is directed backwards rather than forwards. Finally, the question of the mechanical ...

## Variational methods for problems of wave dispersion

Using the generalized variational principle, the article derives the stationary formulas for metallic body dispersion diagram, with variation going to zero for exact values of surface currents, generated on the body by the primary incident wave. Radio engineering and electronics

## About the power, drawn by the receiving antenna from the incident field

Are received various variants of formulas for computing the power, received by the receiver, which take into account the discrepancy between the ends of the feeder path, when the form of the incident wave is arbitrary. In the special case where the receiver is completely concordant with the path, one of them grades into the Burstein-Kinber formula. For different additional conditions, the high bound of the received power is determined and the optimal ...
