چکیده

We propose novel RH-metamaterial structure of the Z-chip for improving the oblique incidence characteristics as an electromagnetic wave absorber. The basic characteristics of a wave absorber using a Z-chip is calculated by FDTD simulation at an oblique incidence. To demonstrate the efficiencies of the chip, a unit cell like a Z-chip was introduced to an actual computer controlled metamaterial electromagnetic wave absorber. The free space method is applied to measure the oblique incident reflection coefficient of the absorber. As a result, it is shown that the TM oblique incidence characteristics were improved the by structural improvement of the chip.

Angle- and Polarization-Insensitive Metamaterial Absorber using Via Array

In this paper, we propose an angle- and polarization-insensitive metamaterial absorber. We design a metamaterial unit cell that is based on a split ring cross resonator (SRCR). We observe that the absorption frequency and absorption ratio are insensitive to incident angles when a via array surrounds the SRR. We demonstrate the effect of the via array using full-wave simulations by comparing the...

Infrared perfect absorber based on nanowire metamaterial cavities.

An infrared perfect absorber based on a gold nanowire metamaterial cavities array on a gold ground plane is designed. The metamaterial made of gold nanowires embedded in an alumina host exhibits an effective permittivity with strong anisotropy, which supports cavity resonant modes of both electric dipole and magnetic dipole. The impedance of the cavity modes matches the incident plane wave in f...

طراحی و بهینه سازی نوعی جدید از مواد جاذب راداری در پهنای باند وسیع و پلاریزاسیون دلخواه به کمک الگوریتم ژنتیک

In this article, a planar multilayered structure is considered as a radar absorber for normal and oblique incidence plane wave. We used actual dispersive material which could be used as a metamaterial for our structure. The formulation can respond any arbitrary polarization i.e. TE or TM. The optimizations are done in a wide frequency band and at a wide range of incident angles that has reached...

X-Band Operations Metamaterial Absorber with Extended Circular Ring Topology for Size Reduction

A metamaterial electromagnetic wave absorber consisting of a big circular ring patch with four smaller suppression circular rings is presented in this report. The metamaterial electromagnetic wave absorber introduces the concept of size reduction by suppressing the resonance frequency. An FR4 substrate was used and the incidental wave angles were varied from 0 0 to 60 0 . Simulations results sh...

A Metamaterial Based Microwave Absorber Composed of Coplanar Electric-field-coup- Led Resonator and Wire Array

Abstract—In this paper, we present a new type of a double-negative metamaterial absorber (MMA) with a periodic array composed of in-plane an electric-field-coupled-LC (ELC) resonator and a wire. In contrast to common MMA configurations, a metallic pattern layer of the proposed absorber is placed parallel to the incident wave propagation direction. An appropriately designed combination structure...
