    ABSTRACT: A novel technique for improving the stability of time domain electric field integral equation (TD-EFIE) method is presented. The method involving the introduction of a new class of temporal basis functions employs a modified form of TD-EFIE to generate stable transient responses from arbitrarily shaped conducting objects, which possesses the advantage of simplicity in implementation. Numerical examples are given to demonstrate the accuracy and the efficiency of the proposed method

    ABSTRACT: The technique to integrate the characteristic modes (CMs) with the asymptotic waveform evaluation (AWE) is proposed for computing the radar cross section (RCS) of an arbitrarily shaped three-dimensional perfect electric conductor (PEC). In the analysis, a few CMs with smaller eigenvalues are chosen to construct the subspace of the solution of a matrix equation. Hence, the solution of the equation can be obtained by combining the based-vectors of the subspace with a set of coefficients, which can be determined by the AWE technique at a given frequency. In addition, the criterion of the spectral radius is found in order that the subspace can be adaptively constructed. Finally, the results of numerical examples prove that the novel technique with CMs and AWE (CMAWE) is effective in widening the extrapolation range.
