Nondestructive electromagnetic material characterization of uniaxial media using a two-flanged rectangular-waveguide technique

A non-destructive technique is presented which allows the determination of complex permittivity and permeability of uniaxial anisotropic media. The technique extends the existing isotropic material characterization two flanged waveguides measurement technique (tFWMT) (M.W. Hyde, et al., A nondestructive technique for determining complex permittivity and permeability of magnetic sheet materials using two flanged rectangular waveguides, PIER-B, vol. 79, pp. 367-386, 2008) to include uniaxial media. The desired constitutive parameters are extracted via comparison of experimentally measured and theoretically derived scattering parameters using a nonlinear least squares method.
