Space constants of auxiliary waves are investigated. In this investigation, validity of space constants of auxiliary waves are examined by cross checking propagation constants and wave impedance under the same polarization. The principal wave considered is a uniform TEM mode electromagnetic plane wave. The auxiliary waves are associated with the principal wave, then various sets of space constants are derived from auxiliary waves based upon the propagation constants or wave impedance of various polarizations.
This approach suggests the existence of a new set of wave impedances for auxiliary waves. This set of space constants shows space constants for auxiliary waves are inhomogeneous and anisotropic for auxiliary waves even though these are homogenous and isotropic for the principal wave. As a numerical example, space constants for free space are sketched for the ¯rst time. The sketch shows indeed space constants of free space for auxiliary waves are inhomogeneous and anisotropic.
