Vector-valued wavelets with triangular support for method of moments applications
W.C. Bandlow, G. Schneider, Arne F. Jacob · IEEE Transactions on Antennas and Propagation · 2005
For a more flexible method of moments analysis of planar circuits, the theory of wavelet transforms is expanded to two-dimensional vector-valued functions with triangular support, the elementary cells being composed of right isosceles triangles. Efficient scaling and matrix sparsity are demonstrated with two suitable examples.
