Abstract

The goal of this work is to examine radar absorbing material (RAM)reflectivity (R)through a frequency (f) range from 0.5 GHz to 40 GHz. Variation of nonmagnetic, homogeneous, and non-dispersive RAMR is reformed to facilitate calculations. Effect of dielectric parameters (E and u) on R for one layer-metal-packed RAM with two different thicknesses are given. Electromagnetic interference shielding effectiveness (EMISE)reflection loss (R), absorption loss (A), and internal loss (M)for one and two layers located between two semi-infinite free space media are derived. Attenuation (a)variations with f, e, u, and layer thickness for single and double layer are given in graphical form.
