Abstract EN
This paper is concerned with the scattering problem of a rectangular cavity.
We solve thisproblem by a least-squares nonpolynomial finite element method.
In the method, we use Fourier-Bessel functions to capture the behaviors of the total field around corners.
And the scattered field towards infinity is represented by a combination of half-space Green functions.
Then we analyze the convergence and give an error estimate of the method.
By coupling the least-squares nonpolynomial finite element method and the Newton method, we proposed an algorithm for the inverse scattering problem.
Numerical experiments are presented to show the effectiveness of our method.
