Abstract :
A novel three-stage approach for preconditioner including loop-tree, basis function rearrangement and incomplete LU is presented. In particular a new technique for construction of loop-tree basis functions for arbitrary-shaped geometries consisting of any number of holes and handles is described. This preconditioner enables fast iterative solution of integral modeling of electromagnetic components in integrated packages.
