| Abstract: | The attenuation of oblique electromagnetic wave propagation in atmospheric plasma layer on a good conductor surface is studied by using Wentzel-Kramers-Brillouin(WKB) approximation.The function distribution of plasma density adapted to plasma cloaking technology is discussed.The attenuation is then numerical deduced and its function of the effects of the negative ions,the angle of incidence and electron collision frequency are taken into account.Parameter dependence of the effects is calculated and discussed. |
