Analysis on the refraction stealth characteristic of cylinder plasma envelopes

The refraction stealth characteristic of two dimensional cylinder plasma envelopes is studied. Firstly, an electromagnetic (EM) problem model of EM-wave propagating through cylinder plasma envelopes is set up. Then EW-wave traces equation in cylinder plasma is derived and a novel concept of plasma refraction deviation angle is presented out. Furthermore, the relation between refraction deviation angle and incidence angle of EM-wave is yielded and the relation between refraction deviation angle and plasma density distribution is made out as well. It is shown that cylinder plasma envelopes could make distinct refraction stealth.
