Analytical asymptotic extraction technique for the analysis of bend discontinuity

The purpose of this paper is to use the analytical asymptotic extraction technique to analyze the bend discontinuity. We show that the derived analytical techniques significantly reduce the computational time while improving the accuracy compared to the conventional method. Especially, the advantage of the proposed method can eliminate the truncation error for evaluating the asymptotic part of impedance matrix. The proposed method has applied for solving the bend discontinuity, and verified with measurement results.
