SYARAT BATAS SERAP PADA GELOMBANG AKUSTIK DUA DIMENSI

Mohammad Mahfuzh Shiddiq

Abstract


Acoustic wave equation with Dirichlet and Neumann boundary conditions cause
incident wave was perfectly reflected at edge. Thus, it is used absorbing boundary conditions
that produce no reflection. In this paper, we would like find approximation of absorbing
conditions that produce reflection coefficient as small as possible and smaller than those
obtained from Dirichlet and Neumann boundary conditions.


Keywords


Wave equation, Absorbing boundary condition, Reflection coefficient.
