Abstract

In this paper, a hybrid analytical method based on the Green´s function is proposed to solve the noise propagation problem between the power and ground planes. This problem is equivalent to a 2-D transverse magnetic problem. A hybrid 2-D Green´s function is derived, which takes advantages of both mode method and imaging method. The major benefit of the proposed method is that it converges quickly at both high frequencies and low frequencies. By the comparison with the full-wave method and measurement results, the accuracy and efficiency of the proposed hybrid method are validated.
