abstract

  • The asymptotic waveform evaluation (AWE) technique [2, 3, 4, 5] is a useful way to minimize repeated electromagnetic system computations for multiple frequencies, dramatically reducing wideband solution times. In the context of AWE, it has already been shown [2,3] that use of the Padé rational function for the modeling of unknowns is a superior choice to the Taylor series expansion, providing a wider bandwidth coverage; owing to its enhanced ability to model pole behavior. This paper discusses a close analog to the Padé rational function developed from the eigenvalues of a given electromagnetic system. For illustrative purposes, we chose the Finite Element Boundary Integral (FE-BI) [7, 8, 9] method to demonstrate the application and utility of AWE expansions based on the eigenvalues of the FE-BI matrix system. © 2005 IEEE.
