Type your question here A 150-MHz uniform plane wave is normally incident from air onto a material whose intrinsic impedance
is unknown. Measurements yield a standing wave ratio of 3 and the appearance of an electric field
minimum at 0.3 wavelengths in front of the interface. Determine the impedance of the unknown
material.
