Abstract
Provided is a waveguide including an input end configured to receive an input wave from an outside; a filtering portion configured to change a frequency range of the input wave; an output end configured to output an output wave of which a frequency range is changed from the frequency range of the input wave; and an inner wall controller configured to control a size of an inner wall of the filtering portion such that the frequency range of the input wave changes to the frequency range of the output wave.
