Modeling of electromagnetic field propation in tunnels
Géze, Daniel ; Motl, Milan (oponent) ; Štumpf, Martin (vedoucí práce)
The submitted master’s thesis aims at the numerical analysis of electromagnetic-wave propagation in tunnels. To this end, an integral-equation formulation has been formulated and numerically solved with the aid of the boundary-element method (BEM). The experimental in-house Matlab implementation shows promisingly low computational demands with respect to the traditional direct-discretization approaches. Sample numerical examples of the electromagnetic-field distribution for various tunnel profiles are given. Validation and post-processing procedures are done by means of a simplified analytical model. The influence of the tunnel profile and its impedance-wall properties on the resulting electromagnetic-field distribution inside a tunnel is demonstrated on numerical examples.
