Application of semiorthogonal spline wavelets and the Galerkin method to the numerical simulation of thin wire antennas

The Bubnov–Galerkin method based on spline wavelets is used to solve singular integral equations. For the resulting systems of linear algebraic equations, the properties of their coefficient matrices are examined. Sparse approximations of these matrices are constructed by applying a cutting barrier. The results are used to numerically analyze thin wire antennas. Numerical results are presented.
