The extreme cases and the non-reciprocal property of the wave propagation along a MMP waveguide

Wave propagation along a plasma waveguide is one of the most interesting and attractive topics in plasma physics and microwave plasma electronics. In the authors´ previous paper (Liu Shenggang et al, Physical Rev. E, vol. 65, no. 3, pp. 036411-1-036411-8, 2002), a lot of interesting and important features in physics were revealed for wave propagation along waveguides filled with moving magnetized plasma (MMPW). A theoretical study on the non-reciprocal properties and the extreme relativistic cases are given in this paper. The numerical calculations show that in a MMPW there exists a non-reciprocal property, and it strongly depends upon the drift velocity of the plasma. As a consequence, the wave propagation in the opposite direction is quite different from that in the positive direction.
