Co-activation of both hemispheres seems to play a critical role in the generation of mirror movements, involuntary muscle contractions opposite to voluntary movements of one hand. The relationship between handedness und mirror movements is unclear. We measured repetitive grip force changes performed at slow and fast frequencies with the active hand and recorded mirror activity in the opposite i...

This letter presents a miniaturized dual-mode compositeright/left-handed line resonator with wide harmonic suppression. The pure right-handed microstrip transmission line adopt 36◦ electrical length instead of 90◦, thus the size of the dual-mode filter can be reduced significantly meanwhile the spurious response suppression are improved effectively. A prototype filter is designed and implemente...

An improved composite right/left-handed (CRLH) unit cell optimized for a leaky-wave (LW) antenna is presented. This CRLH cell consists of a series of one transmission line, an interdigital capacitor, another transmission line and a shunt shorted stub. Introducing the transmission lines, the parasitic self-resonances of the capacitor are shifted outside the operational band, the radiation range ...

This paper presents a realization of composite right/left handed transmission lines using coupled microstrip lines. This structure exploits the advantages of the microstrip lines, while increases the coupling by a floating conductor at the ground plane. The performance of this composite right/left-handed line is demonstrated by both simulated and measured results, and they show good agreement. ...

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...

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...
