Microwave frequencies slotted line
WebThe mode at which a waveguide operates is determined by the: a) shape of the waveguide b) method used to couple the signal into the waveguide c) length of the waveguide d) impedance of the waveguide 55. When does a transmission line have an SWR equal to 1? a) ZL = a b) ZL = Z0 c) ZL = 0 d) G = 1 56. WebStanding waves in a microwave oven are the reason that food is cooked unevenly (the turntable is a partial solution to that problem). The wavelength of the 2.45 GHz signal is about 12 centimeters, or about five inches. Nulls in the radiation (and heating) will be separated at a distance similar to wavelength.
