Recently Epsilon (ε)-near-zero (ENZ) metamaterials have received much attention for several interesting phenomena like supercoupling, transparency and cloaking devices and pattern reshaping at microwave and optical frequencies. Supercoupling effect was theoretically explained and experimentally proved using waveguide by Silveirinha et al and Edwards et al respectively. In this white paper, ENZ phenomenon simulations as well as designs of ENZ Microwave filter using Feko are presented.
