Abstract:
In this letter, the behavior of a recently reported
left-handed metamaterial working at millimeter-wave frequencies
is analyzed. The metamaterial is built by the periodic stacking
of metallic plates with sub-wavelength hole arrays that show
extraordinary optical transmission. If the longitudinal period of
the stacked structure is chosen adequately, it is possible to mold
the electromagnetic wave propagation inside the structure from
right-handed to left-handed. The transmission response of the
fabricated prototype has been measured with a millimeter wave
quasioptical vector network analyzer in the range between 40 GHz
and 110 GHz confirming the possibility to tune the left-handed
or right handed characteristics of the waves propagating there.
These results can give rise to interesting applications such as novel
lenses and other quasioptical structures.
