| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | This research proposes a flux separation method for antenna gain analysis to achieve both high approximation accuracy and high computational efficiency for a radio-telescope antenna consisting of segmented reflector surfaces. To achieve high approximation accuracy, the proposed method considers the effect of diffraction occurring at the segmented reflector boundary by introducing the separation of the flux reflected around gap boundaries into their own and neighboring reflectors with adequately distributed electric field intensities. The efficiency of the proposed method is demonstrated through numerical examples for our proposed balloon-borne smart Cassegrain antenna system. | |
