600-GHz Electronically Tunable Vector Measurement System
The design satisfies a complex set of technical and economic requirements.
A compact, high-dynamic-range, electronically tunable vector measurement system that operates in the frequency range from ≈560 to ≈635 GHz has been developed as a prototype of vector measurement systems that would be suitable for use in nearly-real- time active submillimeter-wave imaging. A judicious choice ...
