WIRELESS COMMUNICATION APPARATUS, WIRELESS COMMUNICATION SYSTEM AND WIRELESS COMMUNICATION METHOD
An aspect of the present invention is a wireless communication device including a water flow generator that controls a shape of a partial region on a water surface, and an emission unit that emits a wave carrying information toward the region.
1 . A wireless communication device comprising:
a water flow generator configured to control a shape of a partial region on a water surface; and
an emitter configured to emit a wave carrying information toward the region.
2 . The wireless communication device according to claim 1 , wherein a shape of the region controlled by the water flow generator is a shape capable of generating only one of a flow of water flowing to the outside from a control region and a flow of water flowing into the control region from the outside.
3 . The wireless communication device according to claim 1 , wherein the shape of the region is convex.
4 . The wireless communication device according to claim 1 , wherein a beam diameter of a wave emitted by the emitter is longer than a wavelength of a fluctuation generated in the region.
5 . A wireless communication system comprising:
a water flow generator configured to control a shape of a partial region on a water surface; an emitter configured to emit a wave carrying information toward the region; and
a receiver configured to receive a signal carrying information using the wave.
6 . A wireless communication method comprising:
controlling a shape of a partial region on a water surface; and
emitting a wave carrying information toward the region.
7 . The wireless communication device according to claim 2 , wherein the shape of the region is convex.
8 . The wireless communication device according to claim 2 , wherein a beam diameter of a wave emitted by the emitter is longer than a wavelength of a fluctuation generated in the region.
9 . The wireless communication device according to claim 3 , wherein a beam diameter of a wave emitted by the emitter is longer than a wavelength of a fluctuation generated in the region.
