Non-Uniform sampling in near field measurement: Experimental results

Abstract

In this paper, the problem of sampling the field radiated by a planar source observed over a finite planar aperture located in the near-field is addressed. In particular, the paper is devoted to assess the performance of the sampling strategy proposed in [9] in a real environment. Accordingly, such a strategy is compared to the classical half-wavelength sampling approach by processing some experimental data. It is shown that in spite of the resulting sampling points are much lower than the ones required by the half-wavelength sampling, the proposed strategy allows to obtain good results.
