The Use of Surface Impedance Boundary Conditions in Time Domain Problems: Numerical and Experimental Validation
نویسندگان
چکیده
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.

متن کاملEfficient Analysis of Plasmonic circuits using Differential Global Surface Impedance (DGSI) Model
Differential global surface impedance (DGSI) model, a rigorous approach, has been applied to the analysis of three dimensional plasmonic circuits. This model gives a global relation between the tangential electric field and the equivalent surface electric current on the boundary of an object. This approach helps one bring the unknowns to the boundary surface of an object and so avoid volumetric...
