| Abstract: | The “step plus ramp model” has been accepted to calculate the coupling of lower hybrid wave with plasma, in which the edge plasma density is assumed to be higher (large than the cut-off density) in the front. The reflected power coefficient and the power spectrum of lower hybrid wave have been validated by solving the wave equation in the areas of vacuum, density plateau and density gradient, respectively, under the conditions of electromagnetic continuity and impedance matching at the edge. The optimal coupling condition of lower hybrid wave with plasma has been explored, and the results obtained from “step plus ramp model” and Brambilla theory has been discussed. |
