Only a few years of rain attenuation data for Earth-space paths are available for low elevation angle paths, and these show a consistent tendency by the CCIR fade prediction model to underpredict rain fades. The authors contribute to the database fou

Ninth International Conference on Antennas and Propagation (ICAP).
Results are presented for four propagation measurement campaigns involving a mobile receiving laboratory and 20 GHz transmissions from the Advanced Communications Technology Satellite (ACTS). The 1994 campaigns were executed during weekly periods in

The results from about 2 years of space and frequency diversity measurements of attenuation, obtained in Austin, Texas, are presented. The data from 11.7, 13.6, 19.04, and 28.56 GHz were analyzed with regard to fade probability, seasonal and diurnal

A complete symposium on the reheat cycle was presented to the Society at the Annual Meeting in 1948. At that time, representatives of the various manufacturers of boilers and turbines reviewed the history of reheat and described in some detail the de

A theoretical investigation of cross polarization generation and radar echo cancellation for the propagation of electromagnetic waves at 17, 30 and 92 GHz through rain is carried out. Both effects are due to canted, nonspherical drops. The canting an
