Abstract
A novel method based on the Padé approximants is proposed to solve efficiently discontinuity problems. The Padé approximants are derived from the squared charactersitic matrices to avoid the singularities in commonly used approximants. Numerical results show the proposed method is very accurate and efficient, especially for cases with negligiblee evanescent waves in the investigated structures. © 2005 IEEE.
