Abstract
Propagation of a transient electromagnetic field in a stratified, dispersive and

anisotropic slab and related direct and inverse problems are investigated. The

field is generated by a transient external 3D source. The analysis relies on the

wave splitting concept and a two-dimensional Fourier transformation in the

transverse spatial coordinates. An investigation of the physical properties of

the split fields is made. To solve the direct and inverse scattering problems,

wave propagators are used. This method is a generalization and a unification

of the previously used imbedding and Green functions methods. The wave

propagator approach provides an exact solution of the... (More)
Propagation of a transient electromagnetic field in a stratified, dispersive and

anisotropic slab and related direct and inverse problems are investigated. The

field is generated by a transient external 3D source. The analysis relies on the

wave splitting concept and a two-dimensional Fourier transformation in the

transverse spatial coordinates. An investigation of the physical properties of

the split fields is made. To solve the direct and inverse scattering problems,

wave propagators are used. This method is a generalization and a unification

of the previously used imbedding and Green functions methods. The wave

propagator approach provides an exact solution of the transmission operator.

From this solution it is possible to extract the first precursor (the Sommerfeld

forerunner). These results also hold for a bi-anisotropic slab. An inverse problem

is outlined using reflection and transmission data corresponding to four,

two-dimensional Fourier parameters. Due to the stratification of the medium,

the inverse Fourier transformation is not needed in the inverse problem. (Less)
