A window-based accelerating algorithm for SDA integration.

Spectral domain analysis (SDA) is presented for solving complex propagation constant of on-chip multi-layer interconnects. As SDA is a full wave solution and is usually computational expensive, a novel bell-shaped window function is introduced to speed up the integral equation (IE). This novel bell-shaped window function has low-pass-filter feature in the spectral domain. Also it has simple closed-form formula which favorites the computational complexity. Based on this window's special feature research, a new accelerating algorithm is derived to speed up the SDA integration. Both the accuracy and the speed of the proposed algorithm are proved to be very promising. [ABSTRACT FROM AUTHOR]
