1. A surface wave generator for propagating a surface signal along a metal surface, the generator comprising:
a radiator configured to generate an electromagnetic field based on a signal externally applied;
a first dielectric substrate positioned on a top of the radiator;
a second dielectric substrate positioned on a bottom of the radiator;
a first surface wave generation member positioned on a bottom of the second dielectric substrate, a first geometric pattern being deposited on a top of the first surface wave generation member;
a third dielectric substrate positioned on a bottom of the first surface wave generation member; and
a second surface wave generation member positioned between the third dielectric substrate and the metal surface, a second geometric pattern being deposited on an upper surface of the second surface wave generation member,
wherein the first geometric pattern and the second geometric pattern are different from each other, and
wherein resonance is configured to be generated through the electromagnetic field generated in the radiator.
