TLDR
A surface communication device of the present invention includes: an electromagnetic wave propagation unit which propagates electromagnetic waves and has a sheet shape; and at least one of a power feeding device unit which is disposed on the electromagnetic wave propag unit in a non-conductive state with the EM-wave propagation unit and feeds the electromagnetic waves to the EME-wave propagator; and a reception device unit that is disposed at the same time and receives the EM waves propagated via the EM wave propagator as discussed by the authors.Abstract:
A surface communication device of the present invention includes: an electromagnetic wave propagation unit which propagates electromagnetic waves and has a sheet shape; and at least one of a power feeding device unit which is disposed on the electromagnetic wave propagation unit in a non-conductive state with the electromagnetic wave propagation unit and feeds the electromagnetic waves to the electromagnetic wave propagation unit, and a reception device unit which is disposed on the electromagnetic wave propagation unit in a non-conductive state with the electromagnetic wave propagation unit and receives the electromagnetic waves propagated via the electromagnetic wave propagation unit. The at least one of the power feeding device unit and the reception device unit includes: an electromagnetic wave coupling unit which transmits the electromagnetic waves to the electromagnetic wave propagation unit or receives the electromagnetic waves from the electromagnetic wave propagation unit; and an electromagnetic wave suppression unit which includes a plurality of conductor unit structures arranged along a surface of the electromagnetic wave propagation unit so as to surround the electromagnetic wave coupling unit, and suppresses leakage of the electromagnetic waves from a space between the electromagnetic wave coupling unit and the electromagnetic wave propagation unit.read more
