    In the theoretical analysis of the harmonic generation due to the interaction of microwave with plasma, it has not been explicitly taken account of plasma oscillations. So the problems, for instance, the frequency dependence of harmonic power have not been elucidated. In this paper, considering an inner electric field of plasma in addition to the external microwave field, a following mechanism is proposed that the harmonic power becomes remarkable, when the applied microwave frequency ω is in resonance with a plasma frequency ωp.
    Solving the Boltzmann and Poisson equations simultaneously by the perturbation method, the harmonic components of the distribution function of electron, the inner electric field are obtained. Further, the current density, the harmonic power and a power conversion ratio are evaluated for the case in which the thermal motion of electrons in plasma may be neglected. In addition, we can show that the power of even harmonics may vanish in the case of the symmetrical discharge post.

    Simon's “short circuit” theory is criticized, which states that the diffusion rate of plasma across the longitudinal magnetic field is larger than that expected from the classical ambipolar diffusion theory, when the ratio of the tube dimension of the field parallel dierction to that of the field parpendicular dierction is rather small.
    A new measuring method for determining the diffusion rate across the magnetic field quantitatively is introduced to check the short circuit theory.
    Within the authors' considerations, there is no diffusion mechanism due to the short circuit effect, and the diffusion is ambipolar independent of the tube dimension.
