The explained method allows for building an efficient algorithm of calculating characteristics of block phased arrays intended for scanning in a limited sector of angles and normal phased arrays with elementwise phasing considering interaction of radiators in the outside space and power wiring circuits.
The given numerical results show the possibility of considering the influence of the attenuator when designing phased antenna arrays.
 



In section of “Publications-Archive” the “Synthesis of anizotropic impedance plane” archival article is published. Author: Y. V. Yukhanov.


In the article the problem of synthesis of anizotropic impedance plane reflecting a plane uniform wave in a given direction at the desired polarization is solved. The distribution of the impedance is expressed analytically and constitutes a periodic structure. The restrictions on the class of the allowable scattering patterns are formulated for the reactive values of impedance. The reflection coefficients of the nonuniform anisotropic impedance plane are obtained. Numerical results are demonstrated.
