RECENT RESEARCH AND DEVELOPMENT ON METAMATERIALS: THEORY, DESIGN AND REALIZATION

摘要

In this review paper, we discuss a new artificial materials with negative permittivity and permeability simultaneously, which is named by metamaterials. Some special characteristics of this supernatural materials are shown. In particular, the abnormal refraction is observed when electromagnetic waves penetrate through a metamaterial prism. Feasibility of fabricating metamaterials based on analysis of equivalent transmission line model in the microwave spectrum and even higher is also shown. Moreover, a method by applying the quasi-static Lorentz theory and numerical method (i.e., the method of moments for solving the electric field integral equation) are presented to figure out the effective constitutive relations of the metamaterials.
