| Abstract: | An X-band waveguide model for experimental demonstration of power transmisson by beamed mi- crowave was developed.Based on that,the principles of xenon lamp and microwave sulphur lamp and their ap- plication to illuminate solar panel in laboratory are simply introduced,some parameters of a specific silicon solar panel providing power for microwave generator are described,microwave in the model is produced by a gunn di- ode and its correct usage is indicated,an expression to estimate electric field of a cylindrical horn in Fresnel re- gion is given and the dependence of transmission efficiency of two identical rectangular horns on distance is shown,mechanism of microwave semiconductor diode is explained,the experimental results of several point-con- tact silicon diodes are summarized. |
