Document Type: JOURNAL ARTICLE Most documents available from AIAA Technical Library Journal Announcement: IAA8504 The paper presents a theoretical study of the effects of the phase fluctuations of a microwave beam over its cross section as it is transmitted on a space-to-ground path on the characteristics of the rectenna system, particularly the efficiency and the width of the rad i ation pa11 ern. The ph ase fluct nations are shown to h ave a s i g ni f i c ant ef f ect on th e r ec ten n a system when th e radius of the spatial correlation of the field over the beam cross section is less than 25 times the wavelength. The results are pertinent to the study of microwave power- transmission in solar satellite power systems. (L.M.)

Document Type: JOURNAL ARTICLE Most documents available from AIAA Technical Library Journal Announcement: IAA8419 An analysis is made of losses arising during the conversion of microwave energy to de energy in Schottky- barrier diodes. The results obtained make it possible to optimize the diode parameters in a wide input-power range (0.1-5 W) and to achieve a considerable enhancement
