This chapter presents the matrix pencil method (MPM) which is a methodology to approximate a given data set by a sum of complex exponentials. The MPM approach is computationally very efficient and quite robust to noise in the data. The MPM has been s

A fast and accurate method is presented for computing far‐field antenna patterns from planar near‐field measurements. The planar near‐field data can be sampled either using a single moving dipole probe or using an array of dipole probes. Near
