<P> Microwaves are a form of electromagnetic radiation with wavelengths ranging from one meter to one millimeter ; with frequencies between 300 MHz ( 100 cm ) and 300 GHz ( 0.1 cm ) . Different sources define different frequency ranges as microwaves ; the above broad definition includes both UHF and EHF ( millimeter wave ) bands . A more common definition in radio engineering is the range between 1 and 100 GHz ( 300 and 3 mm ) . In all cases , microwaves include the entire SHF band ( 3 to 30 GHz , or 10 to 1 cm ) at minimum . Frequencies in the microwave range are often referred to by their IEEE radar band designations : S , C , X , K , K , or K band , or by similar NATO or EU designations . </P>
