For realizing of long text information hiding and covert communication, a binary watermark sequence was obtained firstly from a text file and encoded by a redun
The method of this paper is based on change in the geometrical shape of the reflectarray plane which is similar to a concave shape and with this changing, it is
The need of communication protocols in today’s environment increases as much as the network explores. Many new kinds of protocols, e.g. for information sharing
A variational formulation of the synthesis problem for plane radiating systems according to the prescribed power directivity pattern (DP) is considered. The fun
This paper studies radiation from circumferential slots on cylindrical waveguide by Poynting’s vector method. It can help us to find mutual admittance between
