Analytical Characterization of a Transmission Loss of an Antenna-Embedded Wall

Abstract

An analytical model for an antenna-embedded wall, also called signal-transmissive wall, is presented in this work. In the signal-transmissive wall, multiple antenna elements are distributed periodically on both wall sides, and connected back-to-back through coaxial cables. Numerical full-wave simulations of the signal-transmissive wall are computationally demanding due to the fine meshes required in the cables while having an electrically large wall size. Therefore the simulations above 8 GHz are not feasible even with a powerful cluster computer of the authors’ research site. The analytical model is an attractive alternative to the full-wave simulation of the wall, which combines the individual transmission characteristics of the bare wall, realized gains of antenna elements and cable losses. The analytical model accurately reproduces the full-wave simulated transmission coefficient of the signal-transmissive wall up to 8 GHz for arbitrary polarizations and incident angles of a plane wave. The model therefore allows analyses of the signal-transmissive wall beyond 8 GHz, showing more than 70 dB reduction of the transmission loss at 30 GHz compared to a bare wall.

Development of a method for synthesizing an information-analytical system for assessing the level of information transmission channels protection

“…2), which allows to assert the presence of a data leak in the information transmission channel. The formulated conclusions about the physical justification of the results obtained do not contradict similar conclusions obtained by other authors about the possibility of detecting data leaks in information systems [2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18]. The algorithm for searching for the associative dependence of control features for quickly identifying the presence of a data leak should be constantly used during the operation of the information transmission channel.…”

“…The conducted analysis [2,3,5] shows that expert methods and the method based on the calculation of the correlation between the characteristics are most often used to determine the dependence between the characteristics [5][6][7][8][9][10][11][12][13][14][15][16][17][18].…”
