[仿真]Analysis of electromagnetic field distribution in tunnels by the boundary-element method

Abstract: An efficient numerical approach, based VXR]"W=  
on the boundary-element method, for the analysis O5H9Y}i]  
of electromagnetic field distributions in twodimensional N{-]F|XX  
tunnels with discontinuities such as  BUwONF  
L-bends, T-junctions, and cross-junctions is PQ@L+],C  
described. The side walls of the tunnels are >Z1q j>  
assumed to be lossy dielectric and the surface RZ1 /#;  
impedance approximation is used to determine the K-&V,MI  
boundary condition on the side walls. A computer JWA@+u*k  
program has been developed for tunnels excited M>M`baM1  
by a line current or a TE dominant mode. A comparison a,78l@d(  
of the numerical results with the experimental 9<Kj6t_  
results using microwave simulation shows *Z_C4Tj  
a good agreement except in the vicinity of .. "bDs2E+W
