Use of the Matrix Pencil method to perform high resolution deembedding in electromagnetic measurements

To isolate regions in the time domain it is necessary to carry out wideband measurements. Typically, the resolution in the time domain is limited by the Rayleigh criteria where the resolution of artifacts in the time domain is inversely proportional to the amount of bandwidth in the measured data. However, if we use a model based parameter estimation then it is possible to go beyond the Rayleigh resolution which is called super-resolution. Here it will be illustrated how super resolution can be achieved using a model based parameter estimation method called the Matrix Pencil method.
