This paper aims at simulating the electromagnetic environment inside an enclosed chamber with high conductivity and complicated structure, validating the feasibility of high-speed wireless communications inside aircraft cabins. It first built a characteristic model which represents the propagation scenario of an aircraft component, then simulated the propagation of 77 GHz millimeter wave source through ray tracing method and obtained wireless channel model including power distribution characteristics and delay spread model. Simulated results demonstrated a feature of standing wave distribution inside the structure, and a relatively large attenuation for millimeter wave propagation in such environment. Delay spread is normally less than 10 ns, with a typical characteristic of clustering. It proved that wireless communication at millimeter wave band in such configurations requires necessary channel coding technology to guarantee data transmission rate and system reliability.
