ince you are trying to find two values, you need two equations. Permeability and permittivity will affect both wave speed and wave impedance
Hint: Field amplitude ratio, wave frequency and wavelength are key aspects to this problem.

Generally, relative permittivity is measured using a metallic waveguide or a coaxial waveguide that is filled with the material to be measured [1], [2]. These methods require lots of time and cost in order to process a material to fit in a waveguide without a gap between the metal walls and the dielectric material.relative permeability is defined as the ratio of the material permeability to the permeability of free space (or vacuum), μo, and given as(17.5)μrelative=μμowhere.
