홈페이지논문 초록 (Abstract)
An energy-controlling technique to actively manage the reflective property of waves from solid boundary is presented. As linear wav es propagate through an energy-controlling area, a reduction in wave heights occurs due to energy dissipation,which can be placed und er direct control through the imaginary part of the wavenumber and p hase velocity. Based on this relationship, the present study investiga tes a new method to control reflected waves with desired heights in the mild slope equation model. The method is validated through numerical t ests for various reflection coefficients and the results confirm the promising use of energy-controlling boundary condition for part ial wave reflections.
