在Ka波段内工作的标准增益喇叭天线的反应和辐射近场距离之间的过渡区中的传播场的空间和时间的演变。具有振幅和相位信息的电场分布由矢量稳定的电光场成像系统以最小的侵入性测量。获得一个完整的矢量成像数据集，一个全面的近场传播图，它显示了详细的字段开发在每个波长平面与全相位进展，提出了天线频率为30 GHz。
The spatial and temporal evolution of the propagating fields in the transition region between the reactive and radiating near-field distances of a standard gain horn antenna operating within the Ka-band are presented. Electric-field distributions with amplitude and phase information are measured with minimal invasiveness by a vector-stabilized, electrooptic field-imaging system. Acquiring a complete vector-imaging data set, a comprehensive near-field propagation chart-which shows the detailed field development at each wavelength plane with full phase progression-is presented for an antenna frequency of 30 GHz.
