The extraordinary-mode eigenvalue equation is used to investigate detailed properties of the diocotron instability for sheared, relativistic electron flow in a planar diode. The theoretical model is based on the cold-fluid-Maxwell equations assuming low-frequency flute perturbations about a tenuous electron layer satisfying ..omega../sup 2//sub p//sub b/(x)<<..omega../sup 2//sub c/ and chemically bond..omega..-kV/sub y/(x)chemically bond/sup 2/<<..omega../sup 2//sub c/. The cathode is located at x = 0; the anode is located at x = d; the outer boundary of the electron layer is located at x = x/sup +//sub b/
