A least-squares approximation method for the time-harmonic Maxwell equations

In this paper we introduce and analyze a new approach for the numerical approximation of Maxwell’s equations in the frequency domain. Our method belongs to the recently proposed family of negative-norm least-squares algorithms for electromagnetic problems which have already been applied to the electrostatic and magnetostatic problems as well as the Maxwell eigenvalue problem (see [5, 4]). The s...

A meshless discrete Galerkin method for solving the universe evolution differential equations based on the moving least squares approximation

In terms of observational data, there are some problems in the standard Big Bang cosmological model. Inflation era, early accelerated phase of the evolution of the universe, can successfully solve these problems. The inflation epoch can be explained by scalar inflaton field. The evolution of this field is presented by a non-linear differential equation. This equation is considered in FLRW model...

Interior penalty method for the indefinite time-harmonic Maxwell equations

In this paper, we introduce and analyze the interior penalty discontinuous Galerkin method for the numerical discretization of the indefinite time-harmonic Maxwell equations in highfrequency regime. Based on suitable duality arguments, we derive a-priori error bounds in the energy norm and the L-norm. In particular, the error in the energy norm is shown to converge with the optimal order O(hmin...

The approximation of the Maxwell eigenvalue problem using a least-squares method

In this paper, we consider an approximation to the Maxwell’s eigenvalue problem based on a very weak formulation of two div-curl systems with complementary boundary conditions. We formulate each of these div-curl systems as a general variational problem with different test and trial spaces as done in [12], i.e., the solution space is L(Ω) ≡ (L(Ω)) and components in the test spaces are in subspa...

Least – Squares Method For Estimating Diffusion Coefficient

 Abstract: Determination of the diffusion coefficient on the base of solution of a linear inverse problem of the parameter estimation using the Least-square method is presented in this research. For this propose a set of temperature measurements at a single sensor location inside the heat conducting body was considered. The corresponding direct problem was then solved by the application of the ...
