An Interpolation Scheme for Green’s Function and its Application in Method of Moment
Keywords:Green’s function, impedance matrix, interpolation scheme, method of moment
An interpolation scheme is put forward to accelerate the calculation of free space Green’s function. Through theoretical analysis, a universal rule on how to build value lists for the phase item of Green’s function is discussed. And this rule can guarantee accuracy of the interpolation scheme. Accuracy and efficiency of the scheme are verified in the calculation of impedance matrix for method of moment. Besides, this scheme can also be applied to other applications which contain the calculation of Green’s functions and is especially useful for the analysis of large scale problems. Moreover, this scheme can be combined with other existing improved approaches of method of moment.
