Abstract
In this presentation advances on metallic lenses based on extreme electromagnetic parameters will be shown: either epsilon near zero or epsilon and mu near zero simultaneously. The former is generated by an array of continuous waveguides at cutoff, whereas the latter is composed of stacked subwavelength hole arrays that can be understood as discontinuous waveguides operating below cutoff.
