Detailed numerical analyses on the propagation characteristics of a slow-surface wave mode in the transversely-magnetized partially-filled solid-plasma waveguide have been extended to the frequency region of 70 GHz on the bases of the theory developed in the previous paper. The results indicate the existence of at least two modes of propagation which exhibit the properties of the slow-surface wave. The experimental substantiation of the theoretical results has been carried out at 4 mm wavelength by employing two separate interferometric methods, employing the n-type InSb at the liquid-nitrogen temperature. The experimental results are in good quantitative agreement with the theoretical prediction for one of the two modes. The reduction of the wavelength in the plasma waveguide has been observed directly, from which the phase velocity as slow as 1/3〜1/4 of the velocity of light has been obtained.
