As Inasmuch as there are no natural

As Inasmuch as there are no naturally existing materials with negative , such a different category of artificial materials brings certainly many peculiar electromagnetic phenomena, different physics, and promising applications.5–7 It is well known that in regular right-handed materials
RHMs the behaviors of electromagnetic wave propagation are completely governed by
, solely because
is always unity. From the point of view of crystal optics,RHMs are usually classified into only three distinct categories as optically isotropic, unaxial and biaxial. In LHMs,however, the propagation characteristics of electromagnetic waves are governed by both
and . The appearance of certainly makes the physical contents of the electromagnetic wave propagations very abundant and changes the required
conditions for the above categories in LHMs.
