Reconstruction of Bi-Isotropic Material Parameters from Experimental Data

Författare

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.
