【 摘 要 】

Standard linear analyses of dispersion equations for homogeneous plasmas yield wave modes that are uncoupled and distinct. However, in inhomogeneous plasmas the wave modes are often coupled to each other. For some range of frequencies and angles of propagation, the energy then can be transformed linearly from one mode to another with constant frequency via processes called linear mode conversion (LMC).
