Abstract

A surface wave generator is proposed. The generator may include a radiator configured to generate an electromagnetic field based on a signal externally applied. The generator may also include a first dielectric substrate on a top of the radiator and a second dielectric substrate on a bottom of the radiator. The generator may further include a first surface wave generation member on a bottom of the second dielectric substrate, a first geometric pattern being deposited on a top of the first surface wave generation member. The generator may further include a third dielectric substrate on a bottom of the first surface wave generation member. The generator may also include a second surface wave generation member between the third dielectric substrate and a metal surface, a second geometric pattern different from the first geometric pattern and being deposited on an upper surface of the second surface wave generation member.

Abstract

A ship IoT wireless communication system using metal surface waves is proposed. The ship IoT wireless communication system may include a first access point installed in a first compartment among a plurality of compartments formed in a ship, and a second access point installed in a second compartment among the plurality of compartments. Each of the first access point and the second access point may perform surface wave communication with each other to form a communication network inside the ship. Each of the first and second access points may include a surface wave generator configured to transmit and receive a surface wave through at least one of a floor, a ceiling, or a bulkhead of each of the plurality of compartments.
