Abstract

Impedance matching at the surface of left‐handed materials (LHM) is required for certain applications including a perfect lens. In this study, we present the experimental and theoretical verification of an impedance‐matched LHM to free space. Reflection characteristics of both one‐dimensional and two‐dimensional LHM were investigated. The reflection was observed to be very low at a narrow frequency range. FDTD simulations and retrieval procedures were used to theoretically verify impedance matching. By varying the number of layers along the propagation direction, the ultralow reflection at specific frequencies was shown to be independent of the sample thickness. © 2006 Wiley Periodicals, Inc.

## Abstract Rotation of left‐handed materials (LHM) is presented as tuning technique in this article. For verification of proposed idea, S‐shaped resonator and its two modified cases are chosen as LHM. The frequency bands of these resonators are determined experimentally with and without rotation.

## Abstract In this article, we analyze the illumination by an electromagnetic wave of an air/left‐handed medium (LHM) interface. It is shown that by placing a periodic structure of resistors near the LHM it is possible to suppress or to reduce the surface wave that is present at the interface. For
