Recently, a novel artificial material named Left Handed Metamaterial (LHM) with unique properties of simultaneously negative permittivity and permeability has attracted great attention.

Photonic crystals and left-handed materials are two hot research interests.

A novel left-handed material with wire array in a ferrite-filled TE_(10) rectangular waveguide;

Since the artificial left-handed material was realized in 2001,it has been devoting to design left-handed microwave components and antennas with large bandwidth,low loss and high integration ability.

Presently, photonic crystals (PCs) and left-handed materials (LHMs) are hot research interests for they have intensively potential applications in the fields of optics and microwave.

Investigation on the miniaturization of the microstrip antenna based on the backward wave property of left-handed medium;

The three ways to realize negative re- fraction that are from double negative medium to negative refraction,from left-handed medium to negative refraction, and from photonic crystals to negative refraction are expeounded deeply.

We compared the effect of the interface of two different right-handed materials with that of the interface between right-handed material and left-handed material.

The Goos-Hnchen shift on the surface of uniaxially anisotropic left-handed materials;

There has been a renewed interest in research of Left-handed materials(LHM) in the past few years.

The effects caused by disorder,rotating and cutting in left-handed materials (LHM) are investigated.
