Experimental Estimation of the Longitudinal Component of a Highly Focused Electromagnetic Field

The detection of the longitudinal component of a highly focused electromagnetic beam is not a simple task. Although in recent years several methods have been reported in the literature, this measure is still not routinely performed. This paper describes a method that allows us to estimate and visual...
