Abstract :
A 100-GHz-class live electrooptic imaging camera (LEI-camera), a novel microwave and millimeter-wave instrument, has been implemented for a scheme of W-band wave analyses. The first real-time visualization of W-band waves as phase-resolved images and phase-evolving movies has been successfully demonstrated, and the relevant images and/or movies obtained have been applied to the analyses of 100-GHz traveling waves. In conjunction with complementary numerical simulation approaches, studies have been conducted on a mode interaction between a ZnTe slab waveguide and a free space as well as on the loss tangent effect on W-band wave propagations. On the basis of the observed images and/or movies with live electrooptic imaging camera, some interesting analytical results have been obtained.
