Abstract :
We review recent progress in optical techniques for radio-wave signal measurement in the frequency region from gigahertz to terahertz. This paper highlights a highly-sensitive electro-optic sensor material such as DAST, circuit diagnosis, antenna characterization, millimeter-wave and terahertz-wave imaging of objects.
