| Summary: | Metamaterials are artificial effectively-homogenous electromagnetic structures with properties that are not readily
available in nature, they are periodic structures made up of unit cells. While the field of metamaterial is receiving much
interest, not too many researches have been done to characterize the metamaterial. A few metamaterial unit cells are
chosen to characterize and investigate the propagation of EM waves inside the metamaterial, eigenmode solver in
Computer Simulation Technology Microwave studio (CST MWS) has been used to derive the dispersion diagram. We
found that some unit cells produce pure left-hand (LH) propagation while the others produced composite right/left-handed
(CRLH) propagation. It is also proposed for the unit cells that can be used for wireless applications. |
