Scattering analysis of dielectric objects based on biorthogonal wavelet transform
Xianliang Wu · Journal of Hefei University of Technology · 2008
The PMCHWT equation for solving dielectric scattering problems is derived and applied to the scattering analysis of inhomogeneous dielectric objects.To speed up the solution of the matrix equation,the db97 biorthogonal discrete wavelet transform(DWT) is introduced to sparse processing of the impedance matrix.The scattering characters of homogeneous dielectric objects and inhomogeneous dielectric bodies are analyzed,and the results are compared with those of the electric field integral equation(EFIE) and volume integral equation(VIE).It is shown that the PMCHWT equation can eliminate the interior resonance problem,and the biorthogonal discrete wavelet transform can speed up the solution of the matrix equation.
