Abstract :
This paper reports a novel experimental scheme to intuitively analyze signal wave propagations on RF planar circuit boards. The scheme is based on a live electrooptic imaging camera (LEI camera) and involves real-time visualization of phase evolution in RF wave electric fields. The scheme was demonstrated to be effective at grasping the immediate essence of RF wave propagations. Movie examples were shown stroboscopically for three kinds of circuit patterns. In addition, the behavior of trapped waves in a meander structure was clearly imaged and analyzed.
