Reconstruction of Bi-Isotropic Material Parameters from Experimental Data

Summary, in English
Time-varying wave propagation and time-harmonic wave propagation in biisotropic
materials are reviewed and the connection between the formulations
is established via the temporal Fourier transform. An alternative method
to determine the dispersive properties of a bi-isotropic slab from sinusoidal
scattering data at normal incidence is presented. A numerical example (realistic,
synthetic scattering data) is given to illustrate the theory. Furthermore,
experimental data is presented and used to generate the permittivity, permeability,
and chirality parameters of a specific man-made chiral slab in the range
3.5–18 GHz. On the basis of the results of inversion, the question whether the
passivity concept is too austere is raised.
