Phase-evolving real-time visualization of 100 GHz traveling waves

A novel experimental scheme has been demonstrated for wave analyses in W-band. A system for phase-evolving real-time visualization of W-band waves has been constructed for the first time and has been applied to 100 GHz traveling wave analyses. Analyses on wave images/movies have been performed in conjunction with a numerical simulation approach. Described as an example of the wave analyses is a study on wave interactions between a semiconductor slab waveguide mode and a free space mode.
