The adaptive computation of far field patterns by a posteriori error estimates of linear functionals

P Monk and Endre Süli

This paper is concerned with the derivation of a priori and a posteriori error bounds for a class of liner functionals arising in electromagnetics which represent the far-field pattern of the scattered electromagnetic field. The a posteriori error bound is implemented into an adaptive finite element algorithm, and a series of numerical experiments is presented
