## Article #9

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...
