A sampling type method in an electromagnetic waveguide

We propose a sampling type method to image scatterer in an electromagnetic waveguide. The waveguide terminates at one end and the measurements are on other far field. imaging function is based integrating known over measurement surface directly. design analysis of such factorization data operator given by measurements. We show that peaks inside scatterer, where coercivity factorized play central role. Finally, numerical examples provided demonstrate performance method.
