Microwave usually refers to the electromagnetic wave in the frequency range of 300MHz ~ 300GHZ. Its wavelength is about 1m to 1mm. It can be further subdivided into decimeter wave, centimeter wave and millimeter wave radar plate. Its corresponding frequencies are UHF, ultra-high frequency, SHF and EHF. With the development of modern microwave technology, submillimeter wave with wavelength below 1mm is also regarded as the category of microwave, which is equivalent to further expanding the frequency range of microwave to higher frequencies. Therefore, some literatures also define the frequency range of microwave as 300MHz ~ 3000ghz.
