Numerical studies of left-handed materials and arrays of split ring resonators

Numerical studies of left-handed materials and arrays of split ring resonators.

We present numerical results on the transmission properties of the left-handed materials (LHMs) and split-ring resonators (SRRs). The simulation results are in qualitative agreement with experiments. The dependence of the transmission through LHMs on the real and imaginary part of the electric permittivity of the metal, the length of the system, and the size of the unit cell are presented. We a...

A Compact Ultra-Wideband Filter Based on Left Handed Transmission Line by Using Complementary Split Ring Resonators and Series Capacitor

A compact and sharp rejection UWB microstrip bandpass filter is developed using left handed metamaterials. For realizing a backward-wave propagation medium, two split ring resonator (CSRR) in the back substrate side and also one series capacitor etched in the host line, are used to produce a negative effective ε and μ, simultaneously. Moreover, in the proposed structure, two doublets parallel c...

Miniaturized High-Pass Filter Based on Balanced Composite Right-Left Handed Transmission Line Using Meander Spiral Complementary Split Ring Resonators

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...

Magnetoinductive waves in arrays of split-ring resonators

We study experimentally the propagation of linear magnetoinductive waves in arrays of split-ring resonators with different orientation and spacing. We summarize our experimental results characterizing the effect of coupling of individual elements in magnetic composite metamaterials. We observe the band broadening due to the excitation of magnetoinductive waves which should impose some limitatio...
