“…After the first successful invention of metamaterial by Smith and his colleagues it is being utilized in almost all the applications of electromagnetism because of these exciting electromagnetic properties. The applications of metamaterials have explored in the field of designing filter , designing antenna , efficiency increment of solar cell , building cloak , etc. However, negative refractive index (NRI) property is one of the most important properties of metamaterial to current applied physics researchers.…”

In this article, a negative index metamaterial with two components analysis for C‐ and X‐band operations has been presented. The proposed metamaterial is designed on the epoxy resin composite with woven glass fiber and this epoxy resin formation processes are also explained step by step in this study. The unit cell structure has two arrows and a metal arm is connected to the two arrows that look like a double arrow shaped metamaterial. A Finite Integration technique based CST Microwave Studio is used to figure out the scattering parameters and the designed structure is investigated in the both x‐axis and z‐axis directions. The proposed metamaterial exhibited negative refractive index characteristics with wide bandwidth in S‐, C‐, and X‐band for x‐axis wave propagations. Besides, microwave spectrum in C‐ and X‐band for z‐axis electromagnetic wave transmissions. © 2017 Wiley Periodicals, Inc. Microwave Opt Technol Lett 59:1092–1096, 2017

This paper reveals the design and analysis of a new wideband negative-refractive-index (NRI) metamaterial unit cell. The proposed metamaterial unit-cell exhibits resonance in the C-band and displays negative permittivity and permeability there with a wideband NRI property. It also shows a wider negative peak of the refractive index in the major area of the C-and X-band and minor area of the S-and Ku-band, and a maximum 3-GHz negative bandwidth was achieved compared to the reference metamaterial. In the basic design, a square-shaped copper resonator was constructed with a metal strip on the FR-4 substrate material. The measured result was presented and it shows good conformity with the simulated result. Moreover, an analysis was performed with the same design by replacing the substrate material with the popular Rogers RT 6010 instead of the FR-4 material and then it shows NRI properties in the C-, X-and Ku-band. Keywords: metamaterials, negative refractive index, wideband lanek obravnava zgradbo in analizo osnovne celice novega, {irokopasovnega metamateriala z negativnim lomnim koli~nikom. Predlagana osnovna celica iz metamateriala ka`e resonanco v C-pasu in ka`e negativno permitivnost ter permeabilnost z lastnostmi NRI {irokega pasu. Ka`e tudi {ir{i negativni vrh lomnega koli~nika v ve~ini podro~ja C-pasu in X-pasu in v manj{em podro~ju S-pasu in Ku-pasu. Najve~ja {irina negativnega pasu (3 GHz) je bila dose`ena v primerjavi z referen~nim metamaterialom. Osnovna zgradba je bila konstruirana kot bakren rezonator {tirikotne oblike, s kovinskim trakom na podlagi iz FR-4 materiala. Predstavljeni so izmerjeni rezultati, ki ka`ejo dobro ujemanje z rezultati simulacije. Poleg tega je bila izvedena analiza z enako zgradbo in z nadome{~anjem podlage s popularnim Rogers RT 6010 namesto FR-4 materialom in prikazane so NRI lastnosti v C-, X-in Ku-pasu. Klju~ne besede: metamateriali, negativni lomni koli~nik, {irokopasovnost
