ELECTROMAGNETIC FIELD RECONSTRUCTION FROMNONUNIFORMLY SPACED SAMPLES: A SVD BASED APPROACH

摘要

Purpose of this paper is to furnish a useful technique to recover the electromagnetic field from theknowledge of its nonuniformly distributed samples. It uses the Singular Value Decomposition method todetermine the uniform samples, so that the field at any observation point can be efficiently obtained by applyingthe Optimal Sampling Interpolation algorithm. As demonstrated by numerical results, the reconstruction process isaccurate and stable with respect to errors affecting the nonuniform samples.
