Automatic compensation system for impedance measurement [PDF]
, 2002 This paper deals with the realization of the four-pair terminal definition of impedance standards. A simple, though reliable, system is described that allows an automatic compensation of the voltage at the low potential port of impedance standards to be ...

Skew Incidence on Concave Wedge With Anisotropic Surface Impedance [PDF]
, 2012 The diffraction of a plane wave at skew incidence by an arbitrary-angled concave wedge with anisotropic impedance faces is studied. Concave wedges are of interest in wireless propagation models, in particular on modeling buildings and reflectors.
