| Abstract(in English) | The reduction of radio wave attenuation in rectangular tunnels is discussed.The attenuation of the dominant mode due to its field penetration into a lossy dielectric wall is limited by means of the attachment of wire-netting(mesh).First,a reflection coefficient from a mesh screen over a lossy surface is analytically evaluated.Then,based on a geometrical optical approach to the propagation model,the attenuation of the dominant mode in a rectangular tunnel is derived.The calculated results are compared to a laboratory experiment,which are in good agreement. Finally,the efficiency of attenuation reduction rate by the mesh shielding method is summarized as a function of the ratio of wire interval divided by the wavelength.It is shown that the efficiency of reduction rate by mesh is significant. |
