Passive Reduced Order Macromodeling Based on Loewner Matrix Interpolation

Loewner matrix (LM) interpolation-based macromodeling methods can generate an accurate macromodel for large and complex structures. However, there is less flexibility in the choice of the macromodel order due to the need to ensure passivity. In this paper, an algorithm is proposed to obtain a reduced order model based on LM interpolation while still maintaining the passivity of the macromodel. This is achieved by first relaxing the passivity requirement during the order selection process; then a new passivity enforcement scheme with significantly improved speed and convergence properties is applied. The proposed approach results in a significantly reduced macromodel size while maintaining accuracy and passivity conditions. The efficiency and the scalability of the proposed approach are illustrated by using four numerical examples: three noise-free examples. The results are compared with algorithms proposed in literature. A higher order reduction with better efficiency in terms of computational cost is demonstrated, particularly for both noise-free data and full-wave data subject to discretization noise.

ANSYS HFSS 2014 is used to compute the S-parameter data spanning the bandwidth from 0.05 to 10 GHz. While the passivity enforcement algorithm reported in literature can enforce the passivity of the model obtained from the noise-free data, it fails to enforce passivity of the model obtained from the full-wave data subject to discretization noise due to the passivity violation at DC (f = 0 Hz). However, the proposed algorithm can enforce such a passivity violation. The results for this example are summarized below.
