Abstract :
A simple coherent detection system can accurately measure the attenuation and phase constants of an e.m. wave propagating in a lossy waveguide. The main advantages of the system are its great linearity, sensitivity and versatility. This allows precise measurements on a wide variety of waveguides, even when the losses are very large.
