Sažetak
The transient behaviour of a single straight line embedded in a dielectric half-space and illuminated by the electromagnetic pulse (EMP) is analyzed directly in the time domain using the wire antenna approach. The formulation is based on the corresponding space-time Hallen integral equation. The effects of a two-media configuration are taken into account via the Fresnel reflection and transmission coefficient, respectively. The space-time Hallen integral equation is handled by the time domain version of the indirect Galerkin-Bubnov Boundary Element Method (GB-BEM). The transient response obtained using the direct time domain approach is compared with the results obtained via an indirect frequency domain analysis method. Some illustrative numerical results are presented in the paper. Numerical results obtained via the different approaches agree satisfactorily, i.e the maximum deviation between the results is around 6%.
