Abstract: The present invention relates to a method for acquiring location information of an observation buoy reflecting influence of an ocean current and a method for assessing damage risk relating to spilled oil dispersion of a sunken ship by using same location information. At least one small observation buoy is floated on a target sea area, and a relay buoy collects location information from the observation buoy and predicts ocean current distribution of the target sea area on the basis of the collected information; and the predicted ocean current distribution is applied to a step of predicting spilled oil dispersion in a surrounding sea area so that damage risk relating to spilled oil dispersion of a sunken ship is precisely assessable.

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.
