Abstract

Abstract

Time delay effect on optical dipole antennas space power synthesis is analyzed. Utilizing terahertz time-domain spectroscopy, we obtain terahertz time-domain spectrogram of 34, 500 and 1000 m optical dipole antenna separately. The time delay effect on space power synthesis is studied in numerical simulation. The result shows that, in the condition of 60% space power synthesis efficiency, the relatively biggest time delay of two arrays of 34, 500 and 1000 m optical dipole antenna is 350.7, 467.6, 450.9 fs, respectively, that for three arrays is 191.1, 250.5, 267.2 fs, respectively, and that for four arrays is 167, 200.4, 217.1 fs, respectively. The numerical simulation of space power synthesis can provide important basis for physical experiment of optical dipole antenna arrays.
