A novel backward microstrip coupled-line coupler which has been designed based on the metamaterial and composite right/left handed (CRLH) transmission line (TL) concepts is proposed. Coupling coefficient, bandwidth and size of proposed microstrip coupler are improved by coupled interdigital TLs which have been realized only by one interdigital capacitor. The design procedure to reach the couple...

This study focuses on the deposition and growth mode of rhodium (Rh) on gold (Au) seed nanorods (NRs). Using a combination of scanning transmission electron microscopy imaging, energy-dispersive X-ray spectroscopy, and UV-visible absorption spectroscopy, we show that Rh deposition results in an uneven overlayer morphology on the Au NR seeds, with a tendency for Rh deposition to occur preferenti...

A novel composite right/left-handed (CRLH) coplanar waveguide (CPW)-fed zeroth-order resonator antenna is proposed. The shorted CRLH transmission line exhibits zeroth-order resonance at 2 GHz and operates with narrow bandwidth. The dispersion analysis is also carried out and presented in this article. The proposed antenna has been fabricated and tested. Omnidirectional radiation pattern with a ...

A simple scheme for the realization of terahertz (THz) fundamental-mode tunable closed-stopband composite right/left-handed leaky-wave antennas (CRLH LWAs) is presented. The proposed CRLH LWAs are reconstructed by graphene-based coplanar waveguide (CPW) transmission line supercells. Their shunt inductances achieved narrow graphene strips two unit cell structures halved. designed and confirmed n...

UNLABELLED CRH_Server is an on line Comparative and Radiation Hybrid mapping Server dedicated to canine genomics. CRH_Server allows users to compute their own RH data using the current canine RH map, and allows comparative dog/human mapping analyses. Finally, it suggests multiple options for storage and queries of the dog RH database. AVAILABILITY http://idefix.univ-rennes1.fr:8080/Dogs/rh-se...

In this study, we examined hemispheric differences in corticospinal excitability and in transcallosal inhibition in a selected group of young adults (n = 34) grouped into three handedness categories (RH: strongly right-handed, n = 17; LH: strongly left-handed, n = 10; MH: mixed-handed, n = 7) based on laterality quotients (LQ) derived from the Edinburgh Handedness Inventory. Performance measure...

We investigate the properties of nonlinear envelope pulses developed in a coupled composite rightand left-handed (CRLH) transmission line with regularly spaced Schottky varactors. It is found that the dispersive distortion of the envelope pulses carried by each mode is well compensated by nonlinearity introduced by the varactors. In addition, we numerically observe that the collision of two non...

The propagation and radiation properties of dual composite right/left-handed (D-CRLH) transmission line metamaterials are presented, and validated experimentally with a 1D microstrip prototype. In its fast-wave regime, this structure operates as a leaky-wave antenna capable of backfire-to-endfire radiation scanning with beam squinting smaller than that of conventional CRLH (C-CRLH) antennas. It...
