Millimeter–Wave Propagation in the Mesosphere
George A. Hufford; Hans J. Liebe
Abstract: At heights between 30 and 100 km above Earth, the oxygen absorption lines near 60 GHz together with the geomagnetic field cause the atmosphere to become an anisotropic medium. This report discusses why this is so and how to compute the consequent effects. It describes the computer program ZEEMAN, which allows the user to display in either graphical or tabular form many aspects of how radio waves propagate through this medium.
Keywords: millimeter waves; radio propagation; anisotropic media; mesosphere; oxygen absorption lines; polarization; Zeeman effect
