Th paper considered the propagation behaviour of a circular waveguide enclosing an axial column of anisotropic plasma. We introduced the characteristic equations of propagation region in the waveguides. Then we solved the equations numerically by introducing dimensions of plasma electrondensity, radius, intensity of magnetic field and waveguide radius. The components of electromagnetic field in the waveguide are decided by the above method. Next the Farady rotation angles of polarized wave are calculated. We measured the Farady rotation angles through the plasma waveguides. These angles are tolerably coincide with the calculated values. We constructed the plasma isolators of circular waveguide used the Farady rotation, and measured the forward and the backward attenuations. We think that the plasma isolator has possibility to realize in future after some improvements.
