Summary:
This paper presents wave propagation passing through reactive/radiating near-field regions at the Ka-band. Electric-field distributions with amplitude and phase information are measured noninvasively in the overall near-field regions. An electro-optic field probe and its associated imaging system for vector-stabilized electric field visualization are presented. The spatial and temporal evolutions of the radiating fields at reactive/radiating near-field distances over the aperture of a Kaband horn antenna are discussed in detail.
