Abstract

Millimeter-waves have found applications for communication and control in modern railway operations. This paper concentrates on characterizing millimeter-wave propagation in trains. For this purpose, an oversized imperfect periodically loaded rectangular waveguide is proposed, and the surface impedance approximation is adopted to formulate the problem. The closed-form propagation constants for those important TSM_q,m0, modes are obtained. The numerical results for the propagation attenuation of the dominant TSM_1,10 mode are presented, and the influence of passengers on propagation is discussed
