Numerical study of a novel tunable ferrite-wire chessboard structure LHM compared with the multi-layer structure LHM

A novel tunable ferrite-wire composite chessboard structure LHM has been studied. Numerical simulation results about the transmission characteristics of the structure clearly indicate double negative property. The wider broadband property of this chessboard structure LHM compared with multi-layer structure is explored. All simulation results prove that this structure possesses three advantages: (1) Comparing with the multi-layer structure LHM, the chessboard structure LHM has wider bandwidth and better transmission property. (2) It is easier to realize tunable property. (3) The fabrication requirement on this structure is not critical, which will benefit its practical applications.
