As early as 1968, Veselago theoreti

As early as 1968, Veselago theoretically pioneered the
conceptual materials with simultaneously negative permittiv￾ity
and permeability , called left-handed materials

LHMs.
1 Since the recent leading works of Pendry et al.2
and Smith et al.,
3,4 the related study has become a readily
growing field. Inasmuch as there are no naturally existing
materials with negative , such a different category of arti-
ficial materials brings certainly many peculiar electromag￾netic 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 catego￾ries as optically isotropic, uniaxial 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.

早在1968年初，Veselago理论开创了同时具有负permittiv￾性和渗透性概念的材料，称为左手材料LHMs。1因为Pendry等人近期的主要工作。2和史米斯等人。，3，相关研究已成为一个容易成长的领域。因为没有自然存在的材料与负，这样的一种方法—人工材料带来很多特殊的电磁￾遗传现象，不同的物理，和有前途的应用程序：5、7，这是众所周知的，在规则右撇子材料罗门哈斯电磁波的行为传播是完全受，完全是因为总是统一。从晶体光学的角度，罗门哈斯通常分为三类不同￾里斯光学各向同性，单轴和双轴。在LHMs，然而，电磁波的传播特性波是由两个和。外观一定会使电磁的物理内容波的传播非常丰富和变化的需要在LHMs的上述类别的条件。LH
