We investigate the use of least-squares methods to approximate the Helmholtz equation. The basis used in the discrete method consists of st lutions of the Helmholtz equation (either consisting of plane waves or Bessel functions) on each element of a finite element grid. Unlike p~evious methods of th

An application of least squares finite element method (LSFEM) to wave scattering problems governed by the one-dimensional Helmholtz equation is presented. Boundary conditions are included in the variational formulation following Cadenas and Villamizar's previous paper in Cadenas and Villamizar [C. C
This paper proposes a method for realizing twodimensional (2-D) adaptive filters by applying a onedimensional (1-D) recursive least squares (RLS) algorithm. First, by applying a 1-D RLS algorithm along horimntal and vertical directions, a novel 2-D adaptive algorithm is developed. It is shown that t
