SHAPING THE RADIATION PATTERN WITH MU AND EPSILON-NEAR-ZERO METAMATERIALS

By B. Wang and K.-M. Huang

Full Article PDF (751 KB)

Abstract:
In this paper, mu and epsilon-near-zero (MENZ) metamaterials are used to convert the waves emitted from an embedded line source to various waveforms. The simulation results show that the converted waveforms are consistent with the exit face shape of the metamaterials. The power distributions in different beams are dependent on the length proportion of the exit faces due to its impedance matching with the surrounding media, which is different from the epsilon-near-zero (ENZ) metamaterials. A numerical verification with the finite element method (FEM) was presented, followed by physical insights into this phenomenon and theoretical analysis. We also propose some potential applications, including high directive emissions, multi-beams emissions.
