The recent interest in negative refractive-index (NRI) metamaterials stems from Veselago’s early work predicting media that simultaneously exhibit negative permittivity and negative permeability. Metamaterial structures, such as split-ring resonator and stripwires and planar-loaded transmission line grids, are artificial dielectrics, made of periodically arranged inclusions. Thus, the design of...

An accurate equivalent circuit model for the microstrip line with a complementary split ring resonator (CSRR), and the parameter extraction method, are presented. A highpass filter with steep rejection is designed based on the model. The measurement results confirm the efficient analysis and design procedure and the validity of the highpass filter configuration. DOI: 10.2529/PIERS060906062902

It is shown that the highly resonant characteristic of split ring resonator (SRR) can be significantly improved by introducing new pole pairs to Lorentz atomic model, and by adjusting their resonant frequencies and damping terms. A new SRR cell of metamaterials containing all these required poles is then designed for the desired bandwidth.

In this paper, a compact high-pass filter (HPF) with a sharp rejection response based on the balanced composite right-left handed (CRLH) transmission line (TL) concept is proposed. A series LC resonator using an interdigital capacitor and meander lines is designed. Also, a meander spiral complementary split ring resonator (MSCSRR) is used to realize the parallel LC resonator. The high-pass filt...

This paper presents the results of an investigation into a combination of electric and magnetic planar resonators in order to design the building element of a volumetric metamaterial showing simultaneously negative electric and magnetic polarizabilities under irradiation by an electromagnetic wave. Two combinations of particular planar resonators are taken into consideration. These planar reson...

A three left-handed metamaterial unit cell antenna is presented in this article for ultrawideband applications. Each left-handed metamaterial unit cell is a combination of a modified octagonal split-ring resonator, an octagonal spiral resonator, a capacitance-loaded strip, and a wire in order to achieve a design that simultaneously exhibits both negative electrical permittivity and negative mag...
