Abstract:
The spectrum of electromagnetic waves in ku band has a great impact on equipment and manpower. Many methods have been used to protect electronic equipment against this range of waves. In this paper, uniform and non-uniform cold plasma consisting of three rectangular layers is used. Each plasma layer has different parameters such as thickness, impact frequency, magnetic property, variable density and wavelength of radiation. The electromagnetic input wave with p polarization is considered at different angles in the ku band. By solving the wave equations and calculating the acceptance coefficient in single and triple plasma layers, the optimal value of total absorption and reflection is calculated. Then, using Mathematica software, the diagrams are drawn according to the parameters mentioned in the single-layer blade and the three-layer blade. Using these diagrams, the cop protection coefficient in single-layer and three-layer states is compared by considering consecutive reflections in magnetic and non-magnetic cases, and the desired results are presented. The results show that using three-layer plasma leads the cop coefficient to its optimum for high bandwidth.
