Document Type: JOURNAL ARTICLE Most documents available from AIAA Technical Libi ary J o u rn a1 Ann ouncement: IAA8407 The rectifier circuit of a rectenna element is analyzed with the aim of determining the main relationships between its characteristics and the Scho11ky-barrier di o d e (Au-GaAs) parameters on the one hand and the operating mode of the rectifier on the other. Specifically, the analysis ma k e s it possible to determine the dependence of the power conversion efficiency and input impedance? of the rectifier on the main parameters of the diode, and to optimize diode parameters for specific levels of input power with respect to maximum conversion efficiency.

Country of Pub1ication: United States Document Type: CONFERENCE: PAPER Most documents available from AIAA Technical Library Journa1 Announcement: IAA8 405 There are three sources of the impact. The first has to do with the terrestrial operations connected with the construction of the launching site, the space vehicles, the satellites themselves, and the receiving instal1 ations. The second concerns the? transport operations of the? space vehicles carrying the satellites, and the third the transmission of the solar energy back to earth. The overal 1 impact will comprise the biological effects of electromagnetic radiation, the atmospheric effects of radi a t ion and 1 aunch eff1uents, and the environmentai effects of land requirements and the siting of launch facilities and ground-based energy receivers. The rules of space law that form the legal framework for this situation are set forth. A rudimentary foundation for protection of the environment does exist, thanks mainly to the Space treaty of 1967. The absence in current space law of any rule making it mandatory for states to act in such a way as to preclude any possibility of contaminating the environment is decried. (C. R. )
