Claim Text:
1. An electromagnetic wave propagation medium comprising: a first conductive layer; a second conductive layer; an electromagnetic wave propagation space that is interposed between the first conductive layer and the second conductive layer on upper and lower sides; at least one electromagnetic wave input interface; a plurality of electromagnetic wave output interfaces; long sides in a first direction in which an electromagnetic wave is propagated; short sides in a second direction perpendicular to the first direction; two first end surfaces along the short sides opposite to each other with the electromagnetic wave propagation space interposed therebetween; and two second end surfaces along the long sides opposite to each other with the electromagnetic wave propagation space interposed therebetween, wherein, when a wavelength of the electromagnetic wave in the electromagnetic wave propagation space is λ, and n is an integer, in a case where the first conductive layer and the second conductive layer are short-circuited in an end surface which is one of the first and second end surfaces and which reflects the electromagnetic wave, the more distant the electromagnetic wave output interface is from the electromagnetic wave input interface, the closer to a distance of λ/4+n·λ/2 from the end surface the electromagnetic wave output interface is installed, and in a case where the first conductive layer and the second conductive layer are not short-circuited in the end surface, the more distant the electromagnetic wave output interface is from the electromagnetic wave input interface, the closer to a distance of n·λ/2 from the end surface the electromagnetic wave output interface is installed.
