The Use of Surface Impedance Boundary Conditions In Time Domain Problems: Numerical and Experimental Validation摘要
This paper analyzes the limits of applicability
of the time domain surface impedance concept.
Numerical results obtained by the boundary element
formulation employing time domain surface impedance
boundary conditions (SIBCs) of different orders of
approximation are compared with experimental data and
numerical results obtained using the finite element
method. An analytical formula for evaluation of the error
due to application of the various SIBCs is proposed.
Keywords: Time Domain Solution, Surface Impedance
Boundary Conditions, BEM method.
