Abstract: |
Left-handed medium (LHM) is defined as an artificial
electromagnetic composite medium with simultaneously
macroscopic negative permittivity
and negative permeability. However, traditional LHM
structures exhibit high loss and narrow bandwidth, which
lead to little practical interest of
engineering applications.
This talk describes a novel left-handed waveguide
structure based on the classical LHM theory, a
resonant-slot coupled cavity chain (RSCCC) unit cell is
proposed. The backward and forward transmission
properties are verifed by both eigenmode and time-domain
simulation, which indicate the composite right/left
handed properties. Furthermore, a type of square
waveguide based on RSCCC is designed utilizing a novel
feeding structure. The continuous forward and backward
beam-scanning ability of the leaky
wave slotted array antenna is realized. |
