|Title||TE waves in a cylindrical superlattices (LANs) and left handed material (LHm) waveguide structure|
The propagation characteristics of TE waves in a cylindrical waveguide structure of a lateral antiferromagnetic -non magnetic superlattices (LANs) bounded by a left handed material (LHM) are investigated. We found that, adjusting the thickness of the waveguide to small reduced radius will support backward TE wave modes which can have very large effective index nx. At large reduced radius the forward waves of definite wave index and lower frequency are observed. Larger propagation lengths and constant power of the backward waves are realized by decreasing the values of negative electric permittivity εh of LHm. By decreasing the magnetic fraction f1 of (LANS), the backward waves hare getting higher power.
