| Abstract(in English) | In this paper, approximate solution of scattering field by three-layered dielectric slab is derived under high frequency condition. To bundle or collect the multiple reflected rays inside the slab into the primary reflected and transmitted rays, high frequency asymptotic approximation technique is used. We call the derived primary rays ``collective rays''. By using the new reflection/transmission coefficients in the present collective rays instead of the conventional ones, the internal multiple reflections effect of multi-layered glasses of urban building can be easily included in ray tracing method without increase of the computational cost, so one can efficiently carry out propagation analysis through indoor-outdoor environments. |
