Reflectometer used to measure
Reflectometry uses the reflection of waves at surfaces and interfaces to detect or characterize objects. There are many different forms of reflectometry. They can be classified in several ways: by the used radiation (electromagnetic, ultrasound, particle beams), by the geometry of wave propagation (unguided versus wave guides or cables), by the involved length scales (wavelengt… WebFind many great new & used options and get the best deals for NARDA 3074 high directivity reflectometer set with 5074 and 3094 at the best online prices at eBay!
