1. Calculate the attenuation constant α in [Np/m] of a 1 [GHz] plane wave as it passes through
a medium with a loss tangent of 0.05 if it is known that the medium is nonmagnetic and the
wavelength at that frequency is 17.32 [cm].
2. Calculate the intrinsic impedance ????, the attenuation constant ???? (in [Np/m]), the skin depth ????,
and the wavelength ???? of copper (???? = 5.8 × 107
[S/m], ???? = ????0 and ???? = ????0) at ???? = 60 [Hz].
