Calculation of electrical length variations and focusing-defocusing due to tropospheric layers in microwave propagation
John S. Nicolis; Carolen Moncure
Abstract: Numerical results concerning the disturbances caused by a typical category of slightly subrefractive or superrefractive thick tropospheric layers in line-of-sight propagation as well as the importance of total reflection from such layers. These reflection processes seem to play an important role in tropospheric microwave propagation. In fact, as the calculations indicate, considerable enhancement or fadeout of the received field may be explained satisfactorily in terms of the above mechanisms.
