The Calculation of The Self Impedance In The Spectral Domain.

The calculation of the self impedance in the spectral domain is rigorously investigated. This method handles the strong singularity of the dyadic Green's function in the spectral domain and can be applied to both surface and volume integrals resulting from the moment method analysis of electromagnetic problems. The singular and inefficient spatial domain integration is converted into a double spectral domain integration which can be performed efficiently. The use of a finite value for the upper limit for the spectral domain integration is the only approximation in this method. Compared with spatial domain methods, this method is simple and general, requiring no additional formulations except the spectral domain dyadic Green's function. Numerical results are provided to illustrate this method. [ABSTRACT FROM AUTHOR]
