Simulation and Analysis of Electromagnetic Wave Manipulation by Material with Permittivity and Permeability Very near Zero

Electromagnetic properties of the material with effective permittivity and permeability very near zero (double-near-zero, DNZ) have been simulated based on the finite element method and analyzed all-around. The results of simulation show that DNZ can be used to reshape the phase front of a wave perfectly. It can be used as an angular filter as well. Furthermore, The propagation direction and the shape of phase front of EM wave can be controlled by the device which is constructed by DNZ.
