“Boundary waves and characteristics of slot array”

One of the most efficient methods of numeric research of characteristics of finite antenna arrays is the method suggested in [1]. This method is based on the transformation …

 



The results of the research of characteristics of a finite slot phased array are given. It is shown that boundary waves cause significant change of a side radiation in large arrays when the beam deviation in a single scan sector is at maximum. …


One of the most efficient methods of numeric research of characteristics of finite antenna arrays is the method suggested in [1]. This method is based on the transformation of the mutual resistance matrix into a circulant matrix and iterative procedure of solution of the system of linear algebraic equations with the transformed matrix. Also efficient is another method based on the concept of boundary waves [2], which states that the distribution of current in a finite antenna array with uniform amplitude and phase distribution of waves propagating in the feeder lines, can be represented as a sum of the regular part and the boundary wave propagating from the border of the radiating matter deep into the array...
 



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.
