<\/div><\/div><\/div><\/div>What are microwave measuring devices?<\/h3><\/div>Microwave measuring devices are instruments that use electromagnetic radiation in the microwave range of the electromagnetic spectrum to obtain information about the structure, composition and properties of matter. The microwave range typically extends from frequencies of around 300 megahertz (MHz) to 300 gigahertz (GHz).<\/p>\n

This modified signal is received by another antenna and compared with a reference.
