A Polarizing Screen for Beyond-Line-of-Sight Data Transmission

摘要

Data transmission at radio frequencies at distances greater than the line of sight require a relay (active or passive) visible to both transmitter and receiver. This report contains experimental and theoretical work on a polarizing screen to be used as a passive relay in the data-transmission system. Design criteria for the construction of the polarizing screen are derived and applied in the construction of a small experimental screen. The results are also presented in the form of three families of curves applicable to a wide range of systems. (Author)
