microwave oven

'S' band magnetrons are typically used for microwave oven power sources. They operate in the range of 2-4 GHz. The corresponding wavelengths are 15 cm to 7.5 cm. The screening mesh used on microwave oven doors is sufficiently fine (much smaller than 7.5 cm) that it behaves as a continuous, thin, metal sheet, preventing the escape of the radar energy, yet allowing good visibility of the interior (using visible wavelengths, which are much shorter yet).
